A spdt toggle switch has 3 terminals. Spdts have three terminals.

Spdt slide switch wiring diagram. An spdt switch circuit symbol and an spdt slide switch. Terminal 1 can connect up to any load to power a certain device. A spdt toggle switch has 3 terminals. The 2 coil terminals is where the voltage is placed in order to energize the coil. Another common switch type is the spdt. Below is the schematic diagram of the wiring for connecting a spdt toggle switch.
And terminal 3 can connect to any load to power any device. With slide switches the switching movement is in a linear to and fro fashion. We will now go over the wiring diagram of a spdt toggle switch. Terminal 1 can connect up to any load to power a certain device. Spdts are great for selecting between two power sources swapping inputs or whatever it is you do with two circuits trying to go one place. Terminal 2 is the terminal which receives the power necessary so that the loads on terminals 1 and 3 can be powered.
I recently ran into a wiring problem and made an illustrated post on how i figured out the solution and some guesses as to why i came to the solution i did. Below is the schematic diagram of the wiring for connecting a spdt toggle switch. Single pole double throw spdt relay wiring diagram this is the diagram below to learn all the pin terminals of a single pole double throw spdt relay. Below is the schematic diagram of the wiring for connecting a spdt toggle switch. And terminal 3 can connect to any load to power any device. One common pin and two pins which vie for connection to the common.
One of the most common pieces of circuit bending hardware is the single position dual throw spdt switch. Hopefully it could save some people the hassle of having to rewire their project. Most simple slide switches are of the spdt variety. So a spdt switch can power either one of 2 circuits.
