Steering Wheel Indicator switching
I was thinking of fitting 2 little push button switches to my steering to controll the indicators. One on the LH side and one on the RH side close to
the area where you would rest your thumbs. The idee is to push the switch with your thumb to activate the indicator and when you push it again the
indicator will be cancelled.
As I know nothing about electronics, is there anybody that can explain or help with the design of such a curcuit diagram.
This will eliminate the stalk and keep the indicator switching to a simple press of the thumd.

Why not use latching switches?

As said above. Push to make, push again to break.
This may not be as convenient as you might think.
You will lose the self cancelling function that you get with standard stalks for a start.
Tell them about the bent treacle edges!

the push buttons I had in mind is a basic flush monting switch. Had a look at latching switches, but thy are all a little bulky. the smallest one I
could find in a local distributors catalog had a 12 mm body protruing out to the back (once fitted)
I want to get rid of all the stalks so loosing the self cancelling function is no problem. Lots of people have toggle switches on the dash, but once
strapped in I can not reach my dash.
Was also looking at fitting switch on the tunnel next to the handbrake, but would like to keep my hands on the steering for as long as possible.

Is 12mm really a problem behind the steering wheel?
I would have thought that any push button switch will have approximately the same depth because of the internal spring.
If you are mad keen on momentary action push buttons the you will have to use 'flip/flops and relays (one of each for each side), unless you use
seriously heavy duty transistors for your flip/flops.
Push button operates - flip/flop operates - relay operates - indicator relay.
Push once = indicators on, push again = indicators off.
You should be getting quite good at this stuff by now.

Got this diagram, but sounds like it only creates a pulse.
Where are the electronics boffins?
