Value Pressure & Vacuum Switches

P6 Automatic Reset Switch

Automatic Reset switches, which are the most common type, will change the state of the electrical poles ("cut-in/cut-out") when the pressure crosses the activation point (set point). The electrical state will return to the previous state when the pressure crosses the deactivation point. These switches do not need human interaction to operate.


P7 Manual Reset Switch

Manual Reset switches will change electrical state ("cut-in/cut-out") and lock when the system pressure crosses the increasing activation point. When the system pressure drops to the deactivation point, the switch's electrical state will remain unchanged. An operator must depress the manual reset button in order for the switch to return to its normal (deactivated) state.
