Abstract
A hydraulic brake system metering valve includes an intergal brake switch having at least one pair of contacts. The brake switch contacts are movable between two positions. The combination valve includes a metering valve assembly having an axially shiftable metering rod. One end of the metering rod is adapted to operate the switch contacts. When pressure is initially applied to the brake system the metering rod shifts, causing the brake switch contacts to move from a first to a second position and thereby generate a first electrical signal. Upon release of the brake pressure, the metering rod shifts back, allowing the brake switch contacts to return to the first position and thereby generate a second electrical signal.
