When it comes to wiring a swamp cooler switch, it is important to understand the wiring diagram. With a good understanding of the diagram, you will be able to identify the components and their functions. This article will explain how to wire a swamp cooler switch and provide a wiring diagram for your reference.

What is a Swamp Cooler Switch?

A swamp cooler switch is an electrical device used to control the operation of a swamp cooler. It is usually installed on the wall near the evaporative cooler and is used to turn the unit on and off. It also helps regulate the temperature of the cooler. The switch is connected to the thermostat of the swamp cooler and can be adjusted to the desired temperature setting.

How to Wire a Swamp Cooler Switch?

When wiring a swamp cooler switch, it is important to follow the wiring diagram provided by the manufacturer. The diagram will usually show the location of the switch, the wiring connections, and the power source. The power source can be a 120-volt AC outlet or a 24-volt DC source. If a 24-volt DC source is used, the wiring must be connected to the positive and negative terminals of the power source.

Step 1: Connect the Power Source

The first step in wiring a swamp cooler switch is to connect the power source to the switch. Ensure that the power source is properly grounded before connecting the wires. Connect the black, white, and ground wires to the corresponding terminals on the switch.

Step 2: Connect the Wires to the Switch

The next step is to connect the wires to the switch. Connect the black wire to the “hot” terminal, the white wire to the “neutral” terminal, and the ground wire to the “ground” terminal. Make sure that the connections are secure and that the wires are properly insulated.

Step 3: Test the Connection

Once the connections are made, it is important to test the connection to ensure that the switch is properly wired. Turn on the power source and check the switch for proper operation. If the switch is functioning correctly, then the wiring is complete.


Understanding the wiring diagram of your swamp cooler switch is important before attempting to wire the switch. It is important to follow the manufacturer’s instructions and to test the connection before using the switch. With the right wiring diagram and a little patience, you can successfully wire your swamp cooler switch.
