an inexpensive switch connecting structure is provided capable of avoiding abnormal wear - off or deformation of a contact spring of a supporting plate even if a movement in a basic shape is placed in a timepiece case having a shape different from the movement and a push button is repeatedly used . the switch connecting structure includes a supporting plate attached to cap a movement of a timepiece and provided with a contact spring having a contact portion at a tip brought into contact with a switch contact portion of a circuit board , and a switch regulating plate provided with a switch spring on an outer periphery corresponding to said contact spring and covering at least part of said supporting plate , wherein said switch spring is flexed by operation of an externally operated component attached to a timepiece case , thereby bringing the contact portion of the contact spring of said supporting plate into contact with the switch contact portion of said circuit board . the switch spring of the switch regulating plate acts as an intermediary to properly convey the pressing force from the externally operated component such as a push button attached to the timepiece case having a different shape from the basic shape of the movement .
