AIR PRESSURE RESPONSIVE SWITCH FOR VEHICLE TIRE AND THE LIKE WITH HINGED CONTACT AND DIAPHRAGM
The switch body has an axial opening in one end thereof and a transverse apertured wall at the inner end of the opening. A transverse resilient diaphragm is mounted adjacent to and spaced from the transverse wall whereby to define therewith a chamber. A first electrical contact member is spaced from the diaphragm in opposed relation to the transverse wall, and a second electrical contact member comprising an annular ring portion and an integrally hinged central contact portion is mounted intermediate the diaphragm and the first contact member. The central contact portion of the second contact member is movable with the diaphragm into and out of engagement with the first contact member in response to the air pressure in the chamber.
