Manual Reset Pressure Switch

Manual reset pressure switches feature a button that allows the system to return back to its normal working condition, forcing to push its disc lock back to the switch contact point. This is different than the auto reset function which will automatically return back to the switch contact point.

Otherwise, the manual reset switch is used for overpressure protection for air conditioning and refrigeration applications.

Can be designed with different fitting materials, adjusted to desired pressure ranges, and combined with various electrical connectors.
