Mechanical Press switch PSM-630

Application:

• To maintain and control the air pressure for air
compressors and water pump.

Product Features:
• Pressure range 1-16 bar.

tank of air compressor. Switch gives signal on cut-off
value to stop the air compressor and at cut-in value
again to start the compressor.
• Relief valve or unloader valve is used to release the
pressure over the compressor piston when the electric
motor stops, so that the compressor can re-start without pressure load on piston.
