4 Pieces - Toggle switch on off on
toggle switches, DPDT Mounts in a 1/4" hole.
they are (on-momentary) (off) (on-momentary) so this means that the switch goes to the off position by itself. when you press the switch one way it has power then press it the other way it will reverse. let go of the switch it will turn off.
check out the wiring diagram in the picture to see how to wire it up.
you can reverse a motor with it.
This is the most reliable switch i have ever used.
