This is the toggle part of a PDP-8 panel switch. You can use it to replace all your broken PDP-8 toggles. Like you do.
Special thanks to J. Rubin for sending me an original toggle to measure and cad up.

switch.stl is an approximation of the original PDP switch, with small posts on either side of the switch to hold it in place.

switch2.stl is the same design with the posts removed and a hole drilled down the axis of the switch, so that a stiff wire or nail can be used to make a sturdier toggle.

switch2-base.stl is an adapter that can be attached to a standard slide switch to hold the toggle. (I've used M4 bolts to affix the base to the tabs of the switch.)
