Occupancy Sensor Switch Wiring Diagram: A Comprehensive Guide

Occupancy sensor switches are becoming increasingly popular in homes and commercial spaces. These switches use infrared technology to detect motion and automatically turn the lights on and off based on occupancy. They not only save energy but also provide convenience to the users. One of the most important considerations when installing an occupancy sensor switch is wiring. This article provides a comprehensive guide on occupancy sensor switch wiring diagram.

Basics of Occupancy Sensor Switch Wiring Diagram

Before we dive into the details of occupancy sensor switch wiring, let’s first understand the basics. An occupancy sensor switch typically has three wires: a hot wire, a neutral wire, and a load wire. The hot wire provides power to the switch, the neutral wire completes the electrical circuit, and the load wire connects to the light fixture. When wiring an occupancy sensor switch, it is important to connect these wires correctly to ensure proper functioning.

Additionally, the wiring diagram may vary depending on the type of occupancy sensor switch you are using. Some switches require a ground wire, while others do not. Some switches have a four-wire setup, while others have a five-wire setup. It is important to refer to the manufacturer’s instructions for the specific wiring diagram for your switch.

Wiring Diagram for Single Pole Occupancy Sensor Switch

A single pole occupancy sensor switch is used when you want to control one light fixture from one location. Here is the wiring diagram for a single pole occupancy sensor switch:

Wire Color Description
Hot Black Connects to the black wire from the electrical box.
Neutral White Connects to the white wire from the electrical box.
Load Red Connects to the black wire from the light fixture.

Here are the steps to follow when wiring a single pole occupancy sensor switch:

Step 1: Turn Off Power

Turn off the power to the circuit you will be working on at the circuit breaker or fuse box.

Step 2: Remove Existing Switch

Remove the existing switch from the electrical box.

Step 3: Connect Wires

Connect the wires on the occupancy sensor switch to the corresponding wires in the electrical box according to the wiring diagram above.

Step 4: Mount Switch

Mount the occupancy sensor switch to the electrical box using the screws provided with the switch.

Step 5: Turn On Power

Turn on the power to the circuit at the circuit breaker or fuse box.

Wiring Diagram for 3-Way Occupancy Sensor Switch

A 3-way occupancy sensor switch is used when you want to control one light fixture from two or more locations. Here is the wiring diagram for a 3-way occupancy sensor switch:

Wire Color Description
Hot Black Connects to the black wire from the electrical box.
Neutral White Connects to the white wire from the electrical box.
Load Red Connects to the black wire from the light fixture.
Traveler 1 Red or Black Connects to the same-colored wire from the first 3-way switch.
Traveler 2 Red or Black Connects to the same-colored wire from the second 3-way switch.

Here are the steps to follow when wiring a 3-way occupancy sensor switch:

Step 1: Turn Off Power

Turn off the power to the circuit you will be working on at the circuit breaker or fuse box.

Step 2: Remove Existing Switches

Remove the existing switches from the electrical boxes.

Step 3: Connect Wires at First 3-Way Switch

Connect the wires on the occupancy sensor switch to the corresponding wires in the electrical box at the first 3-way switch location according to the wiring diagram above.

Step 4: Connect Traveler Wires

Connect the traveler wires from the first 3-way switch to the corresponding wires in the electrical box at the second 3-way switch location.

Step 5: Connect Wires at Second 3-Way Switch

Connect the wires on the occupancy sensor switch to the corresponding wires in the electrical box at the second 3-way switch location according to the wiring diagram above.

Step 6: Mount Switches

Mount the occupancy sensor switches to the electrical boxes using the screws provided with the switches.

Step 7: Turn On Power

Turn on the power to the circuit at the circuit breaker or fuse box.
