...any secret to cutting the holes for the switches ? Is panel removal needed, or just a saw blade ? ....

while working on my new dash switches, I found it would be a good time to fix the switch illumination of the old switches as well, so with the lights turned on, all switches will be illuminated again.

So disassembled my winch switch (be careful, there're some small springs and steel balls in there for the switch position which you can easily loose if you're not working on some old cloth or something).
With some fiddling I was able to remove the small bulb which you can see has very long receptables. My local car shop does not have these, so does maybe someone here if MB offers these mini bulbs as replacement parts?

Thanks,

bram.

been there, done that. several times. friendly suggestion: use led's

here's how-to:

great, this is some excellent info, should have known this before starting disassembling myself
guess that's why you're the extreme veteran

thanks again,

The switch is different in that it has one light bar on the bottom and two on the top. Perhaps for two speeds or forward/reverse.

You mean it's like switch for rear windshield wiper and seat heater ( http://www.borderlinebc.ca/borderlinebc/offroad/tech/images/SwitchI... ).

One position is for winding rope on and other position for winding off the winch.

my winch switch only actuates a big relay, so it's more like a master switch than a controller switch to select different types of winch speed or forward/reverse.
the partnumber of this (winch) switch is 002 545 23 07 and it only has got four connections (on/off, light and ground), so really basic on/off switch.

regarding other switches:
the actual switch mechanism of 002 545 11 07 is the same as the 002 545 53 07 as pictured by trc, only the 'shell' determines whether it can only go down, or up and down. So using the 002 545 11 07 as a on/off switch not all pins are used.
Also noticed when disassembling this switch, two springs were installed, but only one metal ball. It actually doesn't need the second spring and ball, since it can only be actuated one way.
On the 002 545 53 07 you will need both springs and balls, other wise it will directly return to neutral position when not pressing the switch in one of the two directions (like on rear window washer switch)

Then, as also can be seen on trc pictures, you can also make a connection on the normally closed position, making it kind of a three way switch. Plenty options to make some nice connections possible.

Last, the on/off indicator light is not really a light. Underneath the small green section, there is a shiny metal plate which act as some kind of mirror when switch is in swtiched position. This is at least the case on switch 002 545 23 07, on my new ordered switches 002 545 11 07 no 'mirror' is present, just the white faces of the switch mechanism.

Yes, it is the same basic switch.

Does that part number on the borderlinebc page refer to the swich or the switch holder?

I have a 463 Heated windscreen switch part number 129 820 74 10. I also functions via a relay and has 2 positions up and down. It has 5 connections on the back presumably for on, off, power, ground, and dash light switch illumination. Does this seem like a correct assumption? I have not bought the harnass yet, but a schematic is on the hanshehl website.

If I wanted to duplicate the function using a 460 switch base like your 002 545 53 07, would I just remove the small balls to allow the switch to return to normal position after being pressed and the relay actuated?
