These compact pressure and vacuum switches are designed and manufactured to exacting standards to meet the needs of OEM manufacturers and instrument makers for a low cost, stable, repeatable switch. Plastic mechanisms and housings are acetal to minimize moisture absorption and maintain dimensional stability. Plastic welding is accomplished using advanced microprocessor controlled ultrasonic welding equipment. All switches are 100% tested at high and low settings and at the proof pressure. Units are delivered with the setpoint at approximately the midpoint of the adjustable range.

CUSTOM SWITCHES
Custom pressure switches are available, with a 50 piece minimum order; please consult Pressure Engineering for price and delivery. Cusotm options include factory setting at specified setpoint, Noryl switch body, Nitrile diaphragm, and DPDT switches can be configured for different pressure settings.
