ABSTRACT:
A diaphragm-type inertia switch for sensing deceleration places the inertial mass in the chamber that contains the contacts. The other chamber has a thin concave-convex shape that gives the switch a low profile. The switch has a molded plastic base containing a test coil for attracting the inertial mass to test the switch. A mechanism for calibrating the switch is also included.
