In other words its like two simple switches controlled by a single actuator. Make sure you dont just use top or bottom screws.
7575 Diagram For Wiring Single Pole Double Throw Toggle
How to wire a single pole double throw switch. 2 methods are explained with associated wiring diagrams. How to wire a 4 way light switch with power feed via the light switch. A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. It is one black wire from the power source hot wire and a black wire from the neighboring switch. An application for this switch is for reversing a direct current dc electrical motor. Use the same clockwise wrapping technique as the ground wire to attach the black cables to the two screws.
A single pole double throw switch can serve a variety of functions in a circuit. Which black wire goes on top or the bottom does not matter. The motors two power leads are reversed at one of the switches screw terminals. A single pole double throw spdt switch is a switch that only has a single input and can connect to and switch between 2 outputs. In this video i give you the characteristics of a dpdt switch and how to wire. Use one screw in the on position and one screw in the off position on the same side.
