HANDBRAKE CONTROLS FOR ROAD VEHICLES

摘要

In a vehicle handbrake control, the operating button of the handbrake carries a bulb which is exposed through a lens positioned in the button. One electrical connection to the bulb is made by a conductive rod which is connected to the handbrake release mechanism and is movable by the button to operate the handbrake release mechanism. Another electrical connection to the bulb is made by way of a hollow conductive member within which the conductive rod is mounted so that an electrical circuit through the bulb can be made to energize the bulb. The circuit also includes a switch so that the circuit can only be completed when the handbrake is operative.
