If you’re replacing a pressure switch, make sure its compatible with your air compressor.Main source of power should be shut off before anything is done.Before connecting terminals and cords, double check the terminal labels and wire colors.Ensure your hands and the surface around you is dry and free of water.Consider wearing protective clothing such as gloves before you start the wiring process.Make sure the wires you intend to use have proper insulation.You should constantly check the efficiency of your pressure switch to determine beforehand if repairs should be done.By following the tips outlined below, you will be well equipped to safeguard yourself. This includes trying to install a wire pressure switch on an air compressor. ![]() When working on any electrical equipment, it’s vital to stay safe. Safety Tips to Consider Before Wiring the Pressure Switch This will allow you to work on the pressure switch seamlessly. What Equipment is Necessary for the Wiring Process?īefore you wire a 220v air compressor pressure switch, you should make sure you have everything you need for the process. This way, grasping the step-by-step guide will be easier.Īlso, by understanding the switch’s role in the air compressor is to regulate the machine’s pressure, you will be more mindful of the wiring process. Start by familiarizing yourself with the different parts of the pressure switch. However, with the right guide, the process will be easy. When you’re wiring a switch for the first time, it may seem like a daunting task. This includes inflating toys and tires and powering tools such as drills, sanders, and nail guns. However, not every owner knows how to wire a 220V air compressor pressure switch.Īir compressors are used in a variety of ways. The double pole switch breaks both wires of the 240VAC at the same time to open the circuit and closes at the same time to make contact and close the circuit.Every home and repair shop benefits from an air compressor. A third green wire is connected to the ground screw. 240VAC double pole switches require both 120VAC hot wire, which are usually a black and red wire connected to the switch. In domestic applications these circuits power clothes dryers, electric ranges, electric hot water heaters or air conditioning window units, that are on a dedicated double pole breaker in your load center. This circuit is typically used on a larger load like a motor or an appliance that requires 240VAC.Ī double pole switch is used with a 240VAC electrical supply. Occasionally the circuit may be on a double pole breaker, making the circuit 240VAC. Single pole and 3-way switches are used for low current 120VAC (Volts of Alternating Current) applications. For the third terminal, one switch is connected to the hot supply wire while the other switch is joined to the light. Two of these take traveler wires that go from one switch to the other. They are wired so either switch can work the light, regardless of the setting of the other.Ī 3-way switch is larger than a single pole switch and has three screw terminals for wiring connections, plus a ground. These are used in pairs, with one at each switching location. In some applications however, such as hallways and larger rooms, having a single switch can be inconvenient, so it might be useful to control the light from two locations, and this is the role of the 3-way switch. There's also a ground wire to protect against electrical faults. It's called a single pole switch because there are two wires connected or separated by the switch mechanism. 3-wayĪ single pole switch is used to control the light in a small closet or bathroom. ![]() It's important to pick the right type of switch for the application. Switches are used to operate lights, fans, and even large electric motors, but they're not all the same.
