P11 manual reset switches will change electrical state (cut-in/cut-out) and lock when the system pressure crosses the activation point. When the system pressure passes the deactivation point, the switch’s electrical state will remain unchanged. An operator must press the manual reset button in order for the switch to return to its normal state. These switches are best utilized in systems that need to be inspected if a maximum pressure has been exceeded, or as safety devices in systems that need human interaction before restarting.
