Supco SHP600475 high pressure switch is suitable to open and close a circuit when the pressure in a system reaches a certain level. They are useful in HVAC/R applications as they prevent damage to the system by shutting it down if the pressure gets too high.
Working Mechanism:
- The pressure switch consists of a piston with one side exposed to fluid pressure.
- The other side is usually at atmospheric pressure.
- The fluid pressure's force is balanced by the force of a preloaded spring.
- The piston moves when a certain pressure is reached.
- The setpoint screw compresses the spring.
- Adjusting the setpoint screw raises or lowers the activation pressure.

- It includes 18-inch lead wires for easy connection with universal HVAC/R equipment.
- This switch has an operating temperature range of -35 to 149 degrees F.
