What is an Intermatic Timer Switch?

An Intermatic timer switch is a device that can be used to control the operation of electrical devices automatically. It works by turning the device on and off at specific times of the day or week. Intermatic timer switches are commonly used in outdoor lighting, pool pumps, and HVAC systems.

Why Use an Intermatic Timer Switch?

There are several reasons to use an Intermatic timer switch:

  1. Energy savings: By controlling when your devices turn on and off, you can save energy and reduce your electricity bill.
  2. Convenience: No more forgetting to turn off the lights or pool pump. An Intermatic timer switch will do it for you.
  3. Security: Use a timer switch to turn lights on and off when you’re away from home to deter burglars.

Wiring an Intermatic Timer Switch

Before starting, make sure you have the proper tools and materials:

  • Intermatic timer switch
  • Wire stripper
  • Screwdriver
  • Wire nuts
  • Electrical tape

Step 1: Turn Off Power

Before starting any electrical work, turn off the power to the circuit you’ll be working on. Locate the circuit breaker in your electrical panel and turn it off.

Step 2: Remove the Cover Plate

Remove the cover plate from the switch you’ll be replacing. Use a screwdriver to remove the screws, then gently pull the cover plate away from the wall.

Step 3: Remove the Switch

Use a screwdriver to remove the screws holding the old switch in place. Gently pull the switch away from the wall, being careful not to damage the wires.

Step 4: Identify and Label the Wires

Identify the wires connected to the old switch. There should be three wires: a black or red wire (the “hot” wire), a white wire (the “neutral” wire), and a green or bare wire (the “ground” wire). If there are more than three wires, consult an electrician.

Label each wire with a piece of electrical tape to indicate its function.

Step 5: Disconnect the Wires

Use a screwdriver to loosen the screws connecting each wire to the old switch. Gently pull the wires away from the switch and set it aside.

Step 6: Connect the Wires to the Timer Switch

Connect the wires to the new Intermatic timer switch. The black or red wire should connect to the “load” terminal, the white wire should connect to the “neutral” terminal, and the green or bare wire should connect to the “ground” terminal.

Use a wire nut to connect each wire to its corresponding terminal. Tighten the screws on the terminals to secure the wires in place.

Step 7: Install the New Switch

Attach the new Intermatic timer switch to the wall using the screws provided. Make sure it is level and secure.

Step 8: Install the Cover Plate

Attach the cover plate to the new switch using the screws provided. Make sure it is level and secure.

Step 9: Turn the Power Back On

Turn the power back on to the circuit you worked on by flipping the circuit breaker back on. Test the new Intermatic timer switch by setting it to turn on and off at a specific time.
