This depends on what yu are trying to achieve?
If you just want to switch 12 volts on and off, there is nio reason why you
shouldnt use a 240 volt mains switch.
If you want to remoteswitch something with a 12 volt signal, you need a
relay or contactor, and because you asked the question you probably nees a
hell of a lot more advice.
Maplin Electronics, amongst other people keep all sorts of bits like this,
they are on line somewhere, but they have a few shops, depending on where
you live. Maplin shops, and most eectronic constructors shops, have the sort
of staff that are willing and able to offer all sorts of solutions to the
problems that most of is don even know exist!
Thanks to all who replied. The car accessories firm will probably be the
answer. I will try next week when in town.
Maplin have a wide range of switches but none of the type I want.
It is simply an on /off switch which is small and is compatible in size to
the cable size
