The Midland Haldex BE13240 is a tractor spring brake circuit light switch designed for air brake systems on heavy-duty trucks. It uses a single-pole, two-terminal design with a 1/8-27 NPT port and actuates at 55 PSI, signaling the brake light circuit when system pressure reaches that threshold. At zero pressure, the circuit is normally closed, making it compatible with standard spring brake warning lamp setups. Sold by Pro Gear and Transmission.
