SUPCO SHP600475 High Pressure Switch Opens 600 Psi

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.
