Robertshaw 2374-495 Air Pressure Sensing Switch

Robertshaw 2374-495 Air Pressure Sensing Switch delivers precision control in a compact, field-adjustable package. The air pressure sensing switch uses a diaphragm operator and is designed for a 0.5 PSI operating setpoint, ensuring tight control with minimal hysteresis. This model is optimized for air as the pressure media and supports applications requiring configurable sensing thresholds.

With SPDT, 2-Circuit contacts and 1/4 inch spade connections, wiring is straightforward for modern control panels. It carries UL and CSA approvals and robust electrical ratings to handle demanding environments: 5 A at 120–277 V AC, 5 A at 28 V DC, and 1 A pilot duty at 120 V. The combination of reliability, adjustability, and convenient connections makes it ideal as an adjustable air sensing switch in HVAC, pneumatic, and automation applications.
