Review on 🚿 LEFOO LF40 Pressure Switch - Ideal for Spa, Hot Tub Pump, Food Waste Disposal, and Air Actuator - Alternate Action, Range 0.25-15psi by Brett Zhu

As one reviewer noted, got it as a detent switch. While I also set up my pushbutton switch as a "latching switch" I was able to reverse the geared cylinder that latches it and have it work as a momentary switch with little effort. It doesn't require a lot of volume or pressure to actuate. This is a traditional SPDT (Com, NO, NC) microswitch snapped into a pressure actuated plunger assembly with a built in ratchet locking mechanism. Simply remove the snap cover and gently pry up on the sides to remove the microswitch. Be careful as two small pieces of ratchet will fall out. Just slide them back in, first the small round knob with arrows, then the serrated barrel, with the serrated end facing out toward the switch so it doesn't snag on the knobs' ratcheting mechanism. Viola! Current/current switch.
