Actuation switch, left hand side. Most commonly used for (but not limited to) 50cc to 300cc ATVs, Dirt Bikes, buggies and scooters. This switch has a large variety of uses though primarily used with a brake lever in order to actuate the brake lights. Secondarily this type of switch is used to toggle activate/deactivate the electric motor on scooters and mobility products, allowing the motor to serve as a generator during braking/deceleration. This brake switch works with our 70A3000 brake lever.
