## Overview

The SensorSwitch WSX Series Wall Mount Motion Sensor combines advanced Passive Dual Technology—PIR and microphonics—to deliver precise, wall-to-wall occupancy detection in commercial indoor spaces. Featuring an integrated dusk-to-dawn photocell, it prevents lights from activating unnecessarily during daylight hours, optimizing energy efficiency. Its innovative wiring design supports installation with or without a neutral wire and prevents wiring errors. Programmable via push-button or app, it offers customizable settings to fit any environment. Durable, UL certified, and backed by a 5-year warranty, this sensor switch is engineered for reliable, hands-free lighting control in offices, restrooms, and small rooms.

## Description

Bring smart, automatic lighting control to busy spaces with the WSX Series Wall Switch Occupancy Sensor. This indoor motion sensor uses PDT dual sensor technology to monitor sound and small movements up to 20 ft. and large movements beyond 36 ft., delivering confident, wall-to-wall coverage in private offices, private restrooms, closets, and copy rooms. As a practical motion detector switch, it supports LEDs, electronic and magnetic ballasts, CFLs, and incandescent lights, and its integrated photocell (disabled by default) can keep lights from turning on when daylight is present. Installation is straightforward thanks to a convertible neutral design that works with or without a neutral, plus interchangeable line and load wires that make it impossible to wire backwards. Time delay and operating modes are push-button adjustable; sensitivity is factory-tuned for reliable detection. Use it as a motion sensor for light, motion switch for lights, or motion light sensor to cut wasted energy while keeping rooms welcoming and hands-free.

## Customer Reviews

### ⭐⭐⭐⭐⭐ wsx pdt
*by V***O on August 27, 2023*

very happy

### ⭐⭐⭐ Not my favorite
*by E***S on October 11, 2023*

These work ok, but they dim and brighten too slow. Makes me feel like they are ancient technology. Something about them just feels cheap. They are good for the price.

### ⭐⭐ No instructions for programing
*by M***S on March 4, 2022*

Switch looks just like the old one but there are no operating or programming instructions.It has instalation intructions. Looked online and the first thing it says it to push a button that is not labeled what they say to push. If you want me to push and hold the on/off button then call it the on/off button. Don't call it the mode button. Also it doesn't tell you what mode your in or an order they come up as you push. Should say push once for time delay or push twice for occupancy. Now I will have to call them, good luck with that. Would not use this switch if it didn't have to be the same one per customer
