ABSTRACT:
This miniature multiplanar acceleration switch has a generally cylindrical electrically conductive mass held by coil spring bias in abutment with one end of a cylindrical chamber in a metal shell. The diameter of the mass is smaller than that of the chamber and is tapered so that the mass can tilt in response to a laterally directed force of acceleration to dispose its axis at an angle to the axis of the chamber. The mass has an inner end formed with a bore into which extends the end of a circuit lead carried by a glass insulator bonded to a header closing the other end of the chamber. When the mass tilts, the lead is contacted by the mass to close an electric circuit.
