ABSTRACT:
An apparatus and method is disclosed for providing an impact switch that is non-critical to temperature variations and preload pressures. The impact switch consists of a plate having a pair of parallel slots disposed therethrough defining a beam capable of flexing. A mass is located on the beam. The plate is covered by a housing having a groove disposed therein and a pin extending through the cover and into the groove. The cover is placed such that the groove is disposed above the beam. When the required force is exerted on the beam it will flex causing the mass and pin to come in contact thereby completing a circuit. The force required to make contact can be varied by changing the mass and/or the material or dimension of the beam.
