Use the same clockwise wrapping technique as the ground wire to attach the black cables to the two screws. Use one screw in the on position and one screw in the off position on the same side.
Single Pole Double Throw Limit Switch Wiring Diagram Diagram
How to wire a single pole double throw switch. A double pole double throw switch is actually two single pole double throw spdt switches. You can see above how a double pole double throw switch can allow a circuit to be in 1 of 2 modes. The motors two power leads are reversed at one of the switches screw terminals. Essentially 2 black wires are attached to the bottom dark screw of one switch. An application for this switch is for reversing a direct current dc electrical motor. In this video i give you the characteristics of a dpdt switch and how to wire.
If the wire end is in poor condition trim off the bare end then strip about 34 inch of insulation using wire strippers. Inspect the end of each wire. A single pole double throw switch can serve a variety of functions in a circuit. This means it has one input terminal and two output terminals. 3 way switch single pole double throw or spdt browse lighting diagrams that use a 3 way switch you may also be interested to see how a two way switch works. Bend the end into a loop using the wire strippers or needlenose pliers.
A double pole single throw dpst switch controls the connections to two wires at once where each wire only has one possible connection. This is how you wire a double pole double throw dpdt switch. It can serve as an on off switch depending on how the circuit is wired. A double pole double throw dpdt switch is a three selection electrical device in which there is one off and two on positions. Which black wire goes on top or the bottom does not matter. It should have about 12 inch of bare wire at the end and should be formed into a hook like loop.
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. 4 way light switch with power feed via the light. Connect the one black wire to the bottom dark screw of the other already wire configured switch. It is one black wire from the power source hot wire and a black wire from the neighboring switch. Double pole double throw switch dpdt circuit. How to wire a 4 way light switch with power feed via the light switch.
In other words its like two simple switches controlled by a single actuator. 2 methods are explained with associated wiring diagrams. Make sure you dont just use top or bottom screws. Below is an example of a circuit which utilizes a double pole double throw switch.
