I'm looking at horn/dip switches and it seems like the best way to fit one on my bars is to use a lever mount one. https://www.feked.com/lucas-type-horn-dip-switch-screw-on-7-8-bars-or-lever-clamp.html Only thing is I've never seen one mounted and it doesn't seem like the angles are right to mount over a standard doherty style lever clamp. Can anyone confirm that something like the above is what I'm after? Anyone have a picture of one mounted?
The mounting bracket that Quinten posted is for a Triumph. The parts page is right out of a Triumph parts book. The perch that Allan posted is the correct perch but the wrong switch. The correct switch is Lucas part no. 31220 and mounts to the back of the perch that Allan posted. Here's a page out of a BSA parts book and one mounted on my Gold Star.
