Handlebar 12mm button switch mount

This is a handlebar mount for a momentary switch for bicycles. I'm using it to add a horn to my ebike. Search for 12mm momentary switch on ebay. I'm using it on a bike mini horn that I rewired to use my switch instead of the one that came with the horn (listed as "120db cycling horn" on ebay for like 8 bucks). Also uses a m4 screw & nut.

Edit: added one with a slight offset of about 10mm over to the side, and the face a couple of mm more forward. Makes it easier to reach in my case.
