Electricity - switch that combines 2 on/off switches

[henk]

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

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.

Here's another alternative :-

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.

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
