1400-384C Pressure Switch

Feature & Principle

It is a mechanical pressure control switch. Process pressure acts on the internal sensing diaphragm or piston assembly. When the pressure reaches the preset threshold, it triggers the snap-action micro switch to realize dry contact on-off signal output. The action set value can be adjusted on site by screw. No external power supply is required for sensing part, stable action and small dead band, used for pressure high/low alarm and equipment interlock protection.
