9000 Series Position Switch

Series 9000 Position Switches retain all of the proven pressure switch design features (snap action, spring calibration, environmental sealing) while providing a hardened stainless steel shaft as the position sensor. Constructed of either stainless steel or anodized aluminum, these switches can be provided in a wide variety of envelopes with varying spring forces for each application.

Incorporating a sealed piston assembly, the Series 9000 Position Switches provide accurate dependable actuation under extreme conditions (shock/vibration/explosion proof).

Position Switches can be provided not only with piston assemblies for in/out requirements (door closing, weight on wheels, blade fold, etc.) but also for side to side (equipment wear, cut of tolerance conditions) applications. Units can be provided with wire leads or electrical connectors to specifications, with a wide range of spring forces available.
