Small radio controlled switch?
 

I've fitted a rather nice steering wheel to the old car which comes with a
horn push in the middle. At the moment the horn is activated by pushing
the indicator stalk. It would be nice to have the push work as well - but
of course this is usually achieved with fairly involved wiring either up
the steering column or with slip rings.
There's a fair amount of room inside the steering wheel boss, so a
battery transmitter and 12 volt receiver elsewhere would be nice. Anyone
seen such a device at a reasonable price anywhere? All I've found are IR
ones.

An interesting idea, these are a fairly standard module:-

At one time RS used to sell them, I'm not sure if they still do.

These ones work particularly well - I have one in my workshop for
remote control of the dust extractor etc. The package of keyfob
plus a multichannel receiver with relay outputs is ideal for that
application - it drives an impulse relay followed by a contactor.

For the horn application, there's more there than needed. However,
RF Solutions supply the electronics modules separately for integration
into something else.

Take a look at suppliers on the car modding scene - I've read of radio
remote switches for switching extra (non-road legal) lighting. I can't
remember any more detail, it's not my scene.

No need to go Radio. Align a couple of coils axially with each other so
that they couple at all positions of the steering wheel. Drive the fixed
coil from an oscillator (555 timer?), and wire the horn button across
the steering wheel coil, maybe with a resistor load. Detect the current
draw from the oscillator to drive a relay for the horn.

Why didn't I think of that? Cheap as chips too.

Looks a bit over specified for what I need - but would be ok if cheap
enough.

Thanks for the kind offer Peter - it certainly looks like it would do the
job.

Interesting idea but might be difficult to arrange in practice.

They are quite good, and if you get a lot of interference fail inert
rather than false triggering. e-mail me your address if you want a
couple to play with.

So you blast your horn and some poor sod with the same tx code answers their
door? Love it. Leave it set at code 0000 like most people who fit wireless
alarms do.

Equally, he can drive along the street pressing his horn and seeing how
many doorbells he can ring. That would be every schoolboy's dream for
knocking on doors and running away.

How long till MOT time Dave? IIRC any horn operaty thingies have to
work if fitted, so you may have limited time to work on this.
