Hydraulic Pressure Switch

Hydraulic Pressure Switch

This is a Nason model MM-1BB-40F/TP130 hydraulic pressure switch used in the hydraulic control systems of rear discharge concrete mixers. The switch is calibrated to actuate at a pressure of 40 PSI. It functions as a normally closed (SPST-NC) switch and is essential for monitoring hydraulic pressure and triggering corresponding electrical responses, such as activating a throttle control. This component is a direct replacement for worn or failed pressure switches, ensuring the hydraulic system operates correctly and safely. It features a brass body with a 1/4" NPT male thread and a male Weather Pack electrical connector for a secure, weather-resistant connection.
