That signal is what tells the rest of the system it is safe to run. When the switch sticks or its contacts stop making, equipment either refuses to start or fails to shut down, and the fault is easy to misread as a bigger problem.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePressure switches from different makers look very similar.
