Additional dash switches?

Are there any OEM Porsche switches that fit in the stock extra blank locations that are on/off type switches? Or are they all just momentary? I have a few things I would like to turn on manually when necessary and don't want to mount ugly aftermarket switches.

Thanks all.

They're all momentary. Can be used as a normal switch if you combine them with a latching relay.

there's a mercedes diesel glow-plug latching relay that does the job (A 002 542 81 10 or Hella 4RC 933 364-00). actually hard to find latching automotive relays for some reason.

I' thinking that you'll need a way to unlatch the relay...unless it's a timed latching relay, so you still would need a separate switch. I would just add an On/Off switch in the Batwing. That's unless you want this ON until you turn the ignition OFF.

i think it is bistable, so another flick of the switch and it unlatches.

I am going to be setting up a switch to trigger the radiator fans using an OEM switch, using a latching relay. Particlewave helped me figure out the wiring in this thread: Defroster Switch Wiring The diagram is originally from Sandy on RennTech.

Another way to do it is to tap into the High Speed and Low Speed relay coil ground wires (pin 86) and use an ON/OFF switch to route to ground. That way you are handling low power controls. That's how I did it and a few others as well.

Not to hijack the thread, but thats what I'm doing with the fan relays, but I want to install an OEM switch to control the on/off function, which requires a latching relaying since OEM switched are momentary.

Are you looking for a relay to replace the OEM one, or adding an additional one between the new switch and he fan relay?

So I have a wire on pin 86 of the high seed fan relays, that is connected to a latching relay, which is connected to the ground. The latching relay is controlled by a momentary OEM switch installed in the dash, to toggle the on/off of connecting pin 86 from the fan relays to ground, which turns the fans on/off. You can see the wiring diagram in this thread: Defroster Switch Wiring

Back to the original topic, you can make most(all?) OEM switches work like on/off switches by adding a latching relay, but you should be aware that the not all of the OEM switches have the same internal wiring if you want things like night time illumination to work, or to use built-in LED's in the switch.

i was under the impression you are still looking for a relay, and wanted to recommend durite 0-728-02.
