Sensor Switch

Sensor Switch Logo

The WSD wall switch sensor is a reliable work horse available with PIR (Passive Infrared) or PDT (PIR+Microphonics™) detection technology. The WSD sensor has several On Modes and Switch Modes that can be programmed using the front push-button. For rooms with obstructions, the Dual Technology WSD PDT Series sensor is recommended. Additionally, all WSD Family sensors have a patent pending wiring method that enables them to function either with or without a neutral connection. WSD units come pre-configured for wiring without a neutral; however, if connection to neutral is required by code, contractors can convert the unit in seconds.
