B&M 1381V Variable Pressure Switch

Description

Pressure switches are a critical part of any fire sprinkler or wet riser system, and widely used throughout. They operate on a fairly basic principle – they open or close an electrical circuit depending on the pressure at which they are set – and therefore they are extremely robust and reliable.

The most popular by far are the Bailey & Mackey LPCB-approved and CE-marked 1381-range, and we hold a large stock of these pressure switches.
