Designed for boiler applications, the MERCOID SERIES 123 is primarily used for low water cut-off or feed-water control. Other applications include condensate tanks and deaerators. A special snap action switch mechanism eliminates frequent operation due to surging water level. A transparent cover provides convenient visible operation of the switch.

Instruments used to measure and display pressure in an integral unit are called pressure meters or pressure gauges or vacuum gauges. A pressure switch is a form

Mercoid pressure switches are available with mercury or snap -action contacts which become an integral part of the ordering number. However switching action is designated by a circuit suffix number. For example, DAW-33-2 would indicate a SPST switch which opens upon an increase in pressure. €, Electrical Ratings,

The company's catalogue includes submersible level transmitters, digital pressure vacuum gauges and pressure & vacuum switches.Mercoid pressure switches are used for actuating one or two SPDT snap switches in response to decreasing / increasing the pressure of compatible liquids or gases. These switches feature a rolling diaphragm design for maintaining an effective area to reduce friction

This pressure switch is designed to actuate one or two single-pole, double-throw (SPDT) snap switches in response to increasing or decreasing pressure of
