Toggle switch......do they make

do they make a 3 position toggle switch were the Middle would be "off", one way be a momentary "on", then the other be a constant "on"?

Yes they are made. Not sure where to get one but they are used in the rear engine compartment on old GMC transit buses if I remember correctly.

Either of these work?

The (on) means momentary...

Painless has a nice one.

Waytek has just about any switch you can think of.

Make sure the switch has the DC current carrying capacity for the circuit where you are using it. AC and DC current capacity are not the same and a lot of switches are only rated for AC use.
