Featured Image for Pressure Switches

These devices are activated by pressure (or lack of pressure) in a high-pressure system.  A piston is connected to a micro-switch that will either complete or interrupt an electrical circuit.  Common applications for them are for turning on/off burners in hot water pressure washers and sending a signal to start or stop an electric motor.  These devices are available in brass or stainless steel.
