Overview

The single pole double throw water flow switch is in the form of electrical contacts: one common moving contact (pole), which can be switched to two static contacts (throw, normally open NO, normally closed NC); When the flow reaches/falls below the set threshold, the contacts switch synchronously - one circuit is connected and the other is disconnected, suitable for interlocking and interruption protection, and dual signal output can be achieved without the need for additional relays.

Single pole double throw water flow switchworking principle

Target type (mainstream mechanical): The water flow pushes the target/blade, overcomes the spring force to produce displacement, and drives the SPDT contact switching of the internal micro switch; When the flow rate is lower than the reset value, the spring will reset the target and the contacts will return to their original state.

The core advantage is single signal triggered dual linkage (1 common terminal+normally open NO+normally closed NC), which can achieve equipment interlocking control and abnormal state alarm simultaneously without the need for additional relays. It is suitable for all water system scenarios that require flow monitoring and dual signal output. The core applications are concentrated in the fields of clean water/clean circulating water, fire water, domestic/industrial water supply, etc
