The thumb lever, also known as trigger, controller features 80 points of resolution for smooth and gradual braking with minimal movement. The thumb lever can be activated with one finger and used for left or right handed individuals. 

To activate the brake, the user gradually pushes the lever to slow and come to a stop. Quickly pushing the lever 4 times (within a 5 second period of time) activates the parking brake. 

The thumb lever controller is powered with a CR2032 battery (3.7V, 190aAh, Li-Polymer). These batteries are easy to find and replace when needed. 

For user's with epilepsy, Parkinson's disease, and seizures, this controller is available with the Smart Brake Switch via special order only.

Includes thumb lever, CR2032 battery, and mount; brake unit sold separately.
