Default Headlight/DashLight Switch Idea

Alright im wondering something. It typically seems that we have problems with our dimming feature on this switch. Is it possible to pull the switch out and rewire it so that it is no adjustable. If im not mistaken its the coil in the bottom part of the switch that constantly goes bad. I have pulled three switches from misc junkyards. And every single one of them has had or done the same thing.

Little bit of brainstorming here see if any of the electrical guys have a good idea.

I did a basic write up on the Switch Failure for the 94. What I think needs to be done is the plastic part that holds the metal ring that slides over the potentiometer needs to be sleeved somehow weather it be with JB weld or another strong epoxy of some sort so that the plastic does not melt and the metal ring does not move freely when it should be tight.

You can see what im talking about in this thread.

I see what your gettin at there but is there a way to disable the ability to dimming the lights which seems to be the major reason this switch gets toasted so often. By making a solid connection rather then a dimming feature. I mean could it be as easy as removing the adjustable and wiring in a direct connection or would that be fire waiting to happen.

I would think that it would be possible with some high wattage resistors. A schematic, careful measurements, and placement of the resistors would be needed.

Have to start with a schematic/wiring diagram for the dimmer.

It is 6c or 6d but it controls the dash lights and the cars running/driving lights

Ill be messing with it a bit when i get off work see if i can go mad scientist style on one of my spare switches.
