- Copper alloy conductors: deliver superior electrical conductivity with low resistive losses.
- Special-design spring and contact arrangement: helps reduce arcing for extended service life.
- 100% tested: every switch is verified for both mechanical and electrical switching performance.
- Build: plastic housing rated for 12-volt operation, with a push-in attachment method, a single rectangular female connector, and two male pin terminals.
Wiring harness, mounting hardware, and mounting bracket(s) are not included. Country of origin: Germany. If a failed stoplight switch is the cause, signs it may need replacing include brake lights that fail to come on when the pedal is pressed or that stay illuminated.
