The Midland Haldex BE13255 is a trailer emergency stoplight switch designed for air-brake systems operating on 12-volt or 24-volt circuits. This single-pole, double-throw, three-terminal switch uses a 1/8-27 NPTF threaded port and actuates at 55 PSI. Below 55 PSI, the TTR and IGN terminals are connected; above 55 PSI, the TTR and TLR terminals connect, controlling stoplight signaling through the trailer's air circuit. The circuit position is normally one open and one closed. Call us to confirm proper fit for your specific trailer application.
