Maplin don't seem to have much in that department, but RS Components have quite a selection. Would need to see the pinout, but I think it is a microswitch with a separate LED and possibly a common ground. If you are stuck to get an exact replacement, it should be possible to construct a replacement out of a separate LED and simple push button switch mounted into a switch blank.

Which part of yours has broken?

Cheers R.

That's correct. I recently installed a Z4 auto-dimming mirror in my Z3 and rewired the alarm led to use the one that sits under the mirror. To replicate the push-button function I installed a momentary contact button into the side of the housing that covers the mirror stalk. As you say, there are three wires from the alarm, one is a common earth, one is power to the led and one is the contact for the switch function.
