These push button switches measure only a bit over 11 mm in diameter which sure is quite small but still they are easy to operate even with winter gloves on. Small adapters which are included allow for a super-clean, gapless installation on convex surfaces like handlebar tubing. Without them you can fasten the button-switches on flat spots like dash covers.

Handy tool for drilling handlebars when installing switches. Prevents drill from slipping and helps to correctly angle the drill bit. The jig is designed to work with 5 mm drill bits and to clamp on 1” handlebars. Professional quality.
