A normally closed, fluid pressure responsive electric switch (10) has an electrically conductive body (12) formed with an orifice (12a) leading to a pressure chamber (12c) which is separated from a switch chamber by a flexible member (14). An annular support plate (18) and disc seat (20...
Apart from “normally open”, manufacturers of pressure switches offer a wide range of switching functions for all applications, such as “normally closed” or “change-over”. “Normally open” and “normally closed” cover well over 95 % of all pressure switch applications, whereas “change-ov...

Pressure switch terminology Let’s first very briefly discuss the related terminology; Normally open / Normally closed Some switches have the switch terminals open when no pressure is connected, callednormally-open(NO) or aclosingswitch. The opposite isnormally-closed(NC) oropeningswitch. The selecti...
If the unit loses power, the relay switches to the Normally Closed position. The user can indicate whether the Normally Closed position is above or below the set point. Using Energize Above the set point as an example, the relay is in the Normally Open position when the pressure is higher...
