WILLIAMS CONTROLS part description

Developed to answer the need for a small modulating and pressure limited type of control. It is available in two versions, one with a single “on” position and another with three “on” positions. Certain vehicles such as school busses and light trucks require a higher degree of operator control than available with simple on-off controls*. With this device, the driver may regulate the stopping force of the spring brakes to meet existing road conditions. Other usage would be as a pressure limited dash control for exhaust brakes.
