Series III Factory Set Variable Differential Pressure & Vacuum Switches With Snap Action Contacts

The Series III switch is a customizable switch built per customer specifications. It features a non-ferrous chamber and excellent set point integrity at extreme temperatures. The exclusive snap switch features: Low-contact resistance, wiping action, fast transfer time, gold over silver contacts, and an adjustable differential. It’s been thoroughly tested for shock and vibration resistance and is particularly valuable in applications where hysteresis, fast transfer time, and low contact resistance are vital.
