Genuine Caterpillar / CAT OEM 374-9690 limit switch assembly. Official CAT parts-book name: SWITCH AS-LIMIT — clutch and brake pedal limit switch (parts-book modifier: brake light). Brand-new CAT OEM stock — not aftermarket, not reman, not take-off.
This is the pedal-actuated limit switch used on Caterpillar clutch / brake pedal groups for stop / brake-light signaling when the pedal is depressed. It is an electrical limit switch — not a pedal assembly, not a position sensor, and not a transmission neutralizer switch.
Use this listing when your Caterpillar parts book, pedal group, or the switch marking shows 374-9690. Fitment is by exact Caterpillar part number and machine serial — not by “brake pedal switch” appearance alone.
