General Purpose Mini Pressure Switches
Quick Specs...
Overview / Design Principle:
These versatile general purpose switches with snap action microswitches can be used in a wide range of hydraulic and pneumatic applications. Their proven piston/diaphragm design offers outstanding accuracy over a very wide pressure range with an outstanding 6000 psi proof pressure. Their modular construction allows Gems to offer a large number of standard pressure fittings in two materials as well as numerous electrical ratings and terminations. Users can easily configure this model to meet their needs.

*These numbers are for the standard microswitch. With either the -SP or 10A option, the values are typically 20% greater than those listed. With the -RD option, the values are typically 25% less than those listed. In certain applications, deadband can be tailored and controlled to customer specifications. Consult factory for details.
