Series V High Pressure Environmentally Sealed, Extreme-duty Switches with Snap Action Contacts

Set Points from 35 to 3000 psi

The Series V switch is a high pressure switch with set points up to 3000 PSI and is built to exact customer specifications. Excellent set point integrity at extreme temperatures and wide fluid compatibility make this switch ideal for extreme duty applications. And, under all operating conditions, it boasts an excellent response time. Like the Series III, the Series V exclusive snap switch has an adjustable differential, low contact resistance, wiping action, fast transfer time, and gold over silver contacts. This switch is beneficial where hysteresis, fast transfer time, and low contact resistance are vital.
