ABSTRACT:
A pressure sensitive electrical switch has a monostable snap disc which is deformed in response to the application of sufficient force. A pressure reducer transmits a force proportional to the pressure of a fluid. The reducer has an annular force transmitting ring which applies force to the snap disc along a circle which is substantially concentric with the disc. By changing the force reducer in a switch to one having a different diameter ring, the operating characteristics of the switch may be changed.
