turning to fig1 a switch 10 according to the present invention is shown . the switch 10 has a supporting and electrically insulating housing 12 . as will become apparent by the following description , the switch 10 could have any shape housing or could differ in operation from the switch hereinafter set forth . the housing 12 includes a rectangular carrier 14 described in detail below . within the carrier 14 are stator contacts 16 ( not shown in fig1 ) each connected to a terminal connector 18 extending to the exterior of the housing 12 . the terminal connectors 18 are adapted to be connected to wires or the like in an electrical circuit . in a known manner , the switch 10 also includes a rotor ( not shown ) in the housing 12 , the rotor having a conductive portion or portions to , upon rotation of the rotor , electrically interconnect or disconnect two or more contacts 16 to provide the switching function for the circuit . to rotate the rotor , the switch 10 includes a shaft 20 extending to the exterior of the housing 12 and having an end 22 with a flat 24 adapted to mount a control knob or the like . a threaded sleeve 26 secured to the housing 12 supports the rotation of the shaft 20 for rotation of the rotor and , in cooperation with a nut ( not shown ), provides the means to mount the switch 10 to a control panel or the like . to fashion the desired pattern of contacts 16 and terminal connectors 18 , the pattern is cut from a sheet 28 of conductive material as shown in fig2 and 3 . the sheet 28 has a top face 29 and a bottom face 30 and , according to the present invention , consists of a contact portion 31 and a terminal connector portion 32 . to impart the desired characteristics of conductivity , flexibility and spring action , the conductive portion 31 consists of a first conductive material , preferably 0 . 006 ± 0 . 0005 &# 34 ; thick 521 grade &# 34 ; c &# 34 ; phosphor bronze , extra - hard temper with a minimum tensile strength of 97 to 112 × 10 3 psi and a rockwell hardness of 30 t . it has been found that when the contacts 16 are fashioned from the aforestated material of the contact portion 31 , that the contacts have the desired flexibility and spring action necessary to bias the contacts against the rotor for proper operation of the switch 10 . to provide a bearing surface to bear against the rotor of the switch 10 , a portion of the contact portion 31 shown as strip 34 extends from left to right across the top face 29 of the sheet 28 as illustrated in fig2 . the strip 34 consists of a layer of low stress nickel inlaid over the contact portion 31 having a thickness of about 0 . 0002 inches with a layer of inlaid gold ( for example , western electric alloy # 1 ) having a thickness of about 0 . 00005 inlaid over the nickel . alternatively , strip 34 may be fashioned from a coin silver alloy having a thickness of about 0 . 0001 ± 0 . 00003 inches inlaid over the contact portion 31 . the strip 34 possesses the characteristics of durability and resistance to wear for the switch 10 . the terminal connector portion 32 is fashioned from a second conductive material , preferably hard copper approximately 0 . 016 ± 0 . 0005 inches thick having on both the top and bottom faces 29 and 30 an inlaid layer of terminal connector tin ( 60 / 40 composition ) alloy approximately 0 . 0002 to 0 . 0004 inches thick . the aforementioned composition of the terminal connector portion 32 imparts the desired characteristics of strength and durability to the terminal connectors fashioned therefrom . to connect the contact and terminal connector portions 31 and 32 to form the sheet 28 , the conductive materials are welded by , for example , electron beam welding to produce a weld 36 shown in fig2 and 3 . a plurality of bores 37 positioned about the sheet 28 to receive pins ( not shown ) hold the sheet 28 during the operations described below . stamping of the desired pattern of contact 16 and terminal connectors 18 from the sheet 28 generates terminal connectors 18a - 18h in the terminal connector portion 32 separated from each other and the remainder of the portion 32 by openings 38a - 38i . each terminal connector 18 has an end tab 40 joining the terminal connector 18 to a border 41 of the portion 32 to support the terminal connectors 18a - 18h during the assembly steps set forth below . for additional support , webs 42a - 42i at the ends of each terminal connector 18 opposite to the tabs 40 extend across the openings 38a - 38i to interconnect the terminal connectors 18 to each other and to the portion 32 . extending from each terminal connector 18b - 18g is a contact 16 stamped from the contact portion 30 of the sheet 28 . each contact 16 has an end 43 disposed in said strip 34 . terminal connectors 18a and 18h are connected to legs 44 and 46 respectively which are part of a contact supporting framework 48 . the framework 48 has a first frame member 50 connected to and supporting the ends 43 of contacts 16 . a second frame member 52 interconnects the ends of the legs 44 and 46 as illustrated in the drawings . to support the framework 48 and the connected contacts 16 , a pair of spaced fingers 54 interconnect the second frame member 52 to the remaining contact portion 31 of the sheet 28 . additionally , flaps 56 connect each leg 44 and 46 and terminal connectors 18a and 18h to the sheet 28 . auxiliary contacts 58 and 59 interconnect the first and second frame members 50 , 52 and have ends 62 , 63 disposed in the strip 34 . depending upon the desired pattern and the structure of the rotor , the auxiliary contacts 58 , 60 may , in cooperation with the second frame member 52 and legs 44 and 46 , provide for the switching between terminal connectors 18a and 18h . either during or subsequent to the stamping of the contact - terminal connector pattern in the sheet 28 , a semi spherical contact surface 66 is formed on the ends 43 of contacts 16 and auxiliary contact ends 62 at the strip 34 . the surfaces 66 when the switch 10 is assembled , bear against the rotor to provide for switching between the contacts 16 and the connected terminal connectors 18b -- 18b , and , due to the material used in forming the strip 34 , possess the desirable characteristic of durability and resistance to wear . to secure the sheet 28 and more particularly the contacts 16 and terminal connectors 18 into a structure to be assembled into the switch 10 , the plastic carrier 14 is insert molded over the sheet 28 . as seen in fig4 and 5 , the carrier 14 has a rectangular body 67 with upper and lower surfaces 68 and 70 . the body 67 covers the weld 36 and accordingly protects the weld 36 from stresses resulting during flexure of the contact 16 or bending of the terminal connectors 18 . to accommodate the flexure of the contacts 16 and rotation of the switch rotor , a central aperture 72 passes between the upper and lower surfaces 68 and 70 of the carrier 14 . the body 67 surrounding the aperture 72 covers , to a great measure , the legs 44 , 46 and second frame strip 52 and a portion of each contact 16 adjacent the weld 36 . accordingly , the body 67 firmly secures the contacts 16 and terminal connectors 18 within the carrier 14 . extending into the carrier 14 from each of the upper and lower surfaces 68 and 70 is a first countersink 73 which defines arcuate contact supports 74 and 76 . the contact support 76 , as seen in fig4 and 5 , covers a portion of the contacts 16 . each contact 16 is free to flex about points 78 at the juncture between the contacts 16 and support 76 thereby protecting the weld 36 from stresses accompanying flexure of the contacts 16 . to accommodate the rotation of the rotor within the switch 10 , the carrier 14 has a second countersink disposed in the upper surface 68 to define opposed , arcuate platforms 84 . the rotor may , for example , bear against the platforms 84 to support the rotation thereof . bores 86 , the lower pair of which extend through openings 37 , pass through the carrier 14 to receive rivets or the like during assembly of the switch 10 . subsequent to the insert molding of the sheet 28 into the carrier 14 , the sheet 28 is trimmed away from the carrier 14 and the border 41 is removed . to separate the terminal connectors 18 and contacts 16 from one another , the webs 42a - 42i are also removed . addition ally , the framework 48 including auxiliary contacts 58 and 60 and the fingers 54 are trimmed to completely free the contacts 16 . since , in the embodiment shown in fig6 terminal connectors 18a and 18h are not required , they are likewise trimmed from the carrier 14 . subsequent to the aforesaid trimming , the contacts 16 are bent about their flexure points 78 in a direction toward the upper surface 68 to , upon assembly of the switch 10 , bear against the rotor thereof resulting in the configuration shown in fig6 . since the contacts 16 are fashioned from a conductive first material exhibiting a biasing spring action , the contacts 16 and more particularly surfaces 66 , will advantageously bear against and maintain contact with the rotor of the switch 10 . furthermore , since the terminal connectors 18b - 18g are fashioned from a relatively rigid material , breakage is prevented . additionally , the flexure of the contacts 16 and bending of the terminal connectors 18b - 18g which may be required to connect the switch 10 to the circuit will not impose undue stress upon the weld 36 which might otherwise cause the weld 36 to break rendering the switch 10 useless . while i have shown and described a specific embodiment of the present invention , it is to be understood that it is subject to many modifications without departing from the spirit and scope of the claims hereinafter set forth .
