Product Features & Applications

Brake switch (Part No. 803644247, type JK231) for XCMG construction machinery — a normally closed (NC), single-pole single-throw (SPST) brake light switch built to the standard JK231 specification. Rated 12V / 24V DC, 3A, with M10×1 fine thread, 2-wire AMP connector, operating temperature -40°C to +110°C . When the brake pedal is depressed, the internal micro-switch actuates, closes the circuit and lights the brake lamp — a critical safety signal to following vehicles . Cataloged as XCMG spare part No. 803644247 (Sinoreach XCMG spare parts catalog ), it is a direct replacement for the failed OE switch, 100% factory tested. The JK231 platform is widely used across light trucks (Dongfeng/FAW/Foton/JAC), forklifts (HELI/Hangcha), and construction machinery — confirm your exact machine model and old-part photo before ordering. Brand new, individually bagged, global shipping.

803644247 JK231 Brake Switch — XCMG-Spec Normally Closed Brake Light Switch (Standard JK231)

The brake switch (Part No. 803644247, type JK231) is an electrical safety component in the braking system of XCMG construction machinery. As a normally closed (NC), single-pole single-throw (SPST) brake light switch, it is normally closed at rest and opens (or switches) when the brake pedal is depressed — depending on circuit design — to control the brake lamp / stop light circuit .

Working principle (per JK231 technical documentation) :

When the driver depresses the brake pedal, the mechanical linkage actuates the internal micro-switch, which switches the circuit and lights the brake lamp. The JK231 uses a 2-wire connection: one wire supplies power, the other is the signal/output to the vehicle electrical system. This simple, robust design provides fast, reliable brake-light response with no delay or flicker.
