Pressure switches act as an interface (safety) switch between a remote-mounted gas pressure regulator and the internal gas unit valve in order to prevent excessive gas solenoid duty cycle. Gas solenoids are used to switch low-pressure pilot gas supply to a main burner in a gas appliance, such as water heaters, ovens, and furnaces.

The main control switch that turns the compressor on and off is called a pressure switch. This is an electro-mechanical device that uses electricity to change from an open to closed circuit when the high side (suction) gas pressure drops below the design cut-out setting.

This pressure switch assembly controls the electric water heater element.
