SPDT On-On
If I remember correctly has 2 postions, up and down.
works like this:
Center pole is feed wire ( 12 volts constant)
Outer poles go to what ever you are feeding power to.
Flipping the switch up usually makes connection between the center pole and the lower pole.
Flipping the switch down usually makes connection between the center pole and the upper pole.
thus Single Throw Double Pole
The On-On referes to the fact that no matter what position the switch is in, one set of contacts or the other set will be making contact. There is no true off postion.
If you are useing the switch to turn on one circuit, just connect feed to center pole and what you want turned on to either of the outer poles, The circuit will be on or off depending on what way you have the switch flipped.
Hope this helps
