henk Posted May 8 Share Posted May 8 For switching between maps on my td5 I am looking for a turnable switch with 4 positions that can replace 2 off/on switches but without working with diodes or so. I need: off/off = standard map off/on = road fast on/off = offroad on/on = 1500 rpm for winching Current switch I use has 4 positions but I can use only 3 of them Quote Link to comment Share on other sites More sharing options...
TSD Posted May 9 Share Posted May 9 Do the switches have to be isolated, or can they be common at one side? And is it just low current inputs to an ECU? If it's something like A Open B Open A Ground B Open A Open B Ground A Ground B Ground Then you might be able to find a BCD switch and just use the lowest 2 bits. Something like https://uk.rs-online.com/web/p/pushwheel-switches/0334123 would work. It would just repeat 0-3, 4-7, 8-9. There used to be wafer switch kits for building rotaries in any combo that was wanted, but I've not seen them for years. If you like the pushwheel, I could probably find one or two for you to play with. Quote Link to comment Share on other sites More sharing options...
TSD Posted May 9 Share Posted May 9 Here's another alternative :- https://uk.rs-online.com/web/p/rotary-switch-wafers/2832539 No diodes required but a tiny amount of extra wiring. Input 1 to terminal A Output 1 to terminals 2 and 4 (joined) Input 2 to terminal B Output 2 to terminals 7 and 8 (joined) No stock at RS, but apparently available from Distrelec in Holland.

henk Posted May 10 Author Share Posted May 10 That is more the solution I am looking for! Thanks for the help I now use a 4 position double pole switch but it is limited to 3 possibilities (off-off, on-off, off-on), the on-on is not possible just like that Quote Link to comment Share on other sites More sharing options...
