When it comes to electrical wiring, a single pole double throw switch (SPDT) is a critical component. What makes this switch unique is its ability to switch between two different circuits, allowing you to control which circuit is active at any given time. Installing and wiring an SPDT switch can be a bit daunting, but with a proper wiring diagram, the job is much easier.
An SPDT switch consists of two separate circuits that are connected together by two sets of contacts, one set for each circuit. The two circuits are separated into input and output terminals. As the switch is moved, the two sets of contacts can be connected or disconnected. This allows you to switch power between the two circuits, activating one and deactivating the other.
To properly wire an SPDT switch, start by connecting the common (COM) terminal to the power supply. Then connect the input terminals to the desired circuits. Finally, connect the output terminals to the desired circuits. Once the wiring is complete, the switch will be able to switch between the two circuits.
When wiring an SPDT switch, it’s important to pay attention to the polarity of the input and output terminals. It’s also important to use the correct size and type of wire for the job. A wiring diagram for a SPDT switch can provide all the necessary information to ensure that the wiring is done correctly. With the help of a wiring diagram, you can easily install and wire an SPDT switch.
