Series A9 Snap-Action Pressure Switch

The Series A9 switch provides reliable snap action switching at preset pressure thresholds. Its mechanism activates or deactivates circuits instantly once the pressure setpoint is crossed, ideal for control and safety interlocks. Adjustable setpoints, rugged diaphragms, and durable contacts make it useful in hydraulic, pneumatic, or process systems. Housings are sealed to resist ingress of dust and moisture. Calibration readiness and local adjustment help maintain switching accuracy and system integrity.
