Handlebar mount 1299 / SL
Shell clamp switches offer a traditional design with a front and rear body to clamp around the handlebar. Robust, very crash-resistant and typically cheap and easy to repair. They do however take up more space on the handlebar so for bikes with Ride By Wire throttle systems, or those with thumb brakes you may be better with the Type-C design which mounts on the brake/clutch
Shell clamp designs are available from 2 to 5 switch positions, or an extra 2 on the rear.
