Power Window Switches

Each Power Window Switch is a two position spring loaded switch. When pressure applied to the switch in either direction is released the switch will return to a middle neutral position.

The Power Window Switches provides a switched ground signal to the BC1 requesting window activation. A momentary touch of the switch (less than 400ms) activates the one-touch operation. A longer touch of the switch (more than 400ms) signals the BC1 for conventional window operation.
