Hero Genuine Rear Brake Light Stop Switch for HF 100, HF Deluxe, Splendor Plus, Splendor iSmart, Passion Pro, Passion XPRO, HF Dawn & Splendor NXG Self-Start Models | 35350KWA940S

Hero Genuine Rear Brake Light Stop Switch – Self-Start Models – 35350KWA940S

Restore correct rear brake-lamp operation with the Hero Genuine Switch Assembly, Rear Stop (Self), part number 35350KWA940S. This rear brake-pedal-operated electrical switch is used on compatible self-start variants of Hero HF 100, HF Deluxe, Splendor Plus, Splendor iSmart, Passion Pro, Passion XPRO, HF Dawn and Splendor NXG motorcycles.

When the rider presses the rear brake pedal, the stop-switch mechanism closes the brake-light circuit so the rear brake lamp illuminates and warns traffic behind that the motorcycle is slowing or stopping. A worn, internally faulty, corroded, incorrectly adjusted or damaged switch can cause the brake lamp to remain off, stay continuously illuminated or operate only intermittently.

This listing is specifically for the self-start-model rear stop switch. It must not be confused with Hero part number 35350KWA930S, which is separately listed as the rear stop switch for applicable kick-start configurations.

Compatibility boundary: Fitment depends on the motorcycle’s start configuration, rear brake-pedal layout, spring arrangement, electrical connector and production generation. A shared model name does not guarantee that every kick-start, self-start, i3S, IBS, CBS or later-generation version uses the same switch.

Fitment Note / Return Prevention Note

Before ordering, match the complete Hero part number 35350KWA940S or catalogue number 35350-KWA-940 with the motorcycle’s chassis/VIN-based Hero parts catalogue.

Confirm all of the following:

• Exact motorcycle model and production generation
• Self-start configuration where the catalogue distinguishes self and kick models
• Existing switch body and threaded mounting design
• Electrical connector and wire length
• Rear brake-pedal spring arrangement
• Switch mounting position and adjustment range
• Part number printed on the original packaging, switch or invoice

Do not confuse self and kick variants:

• 35350KWA940S / 35350-KWA-940 — rear stop switch for compatible self-start configurations
• 35350KWA930S / 35350-KWA-930 — separate rear stop switch for applicable kick-start configurations

The stop-switch operating spring is separately catalogued and may vary between model generations. Do not assume the spring, bracket, fastener or wiring repair connector is included with this switch.

A non-working rear brake lamp may also be caused by a failed bulb or LED tail-lamp assembly, blown fuse, damaged wiring, loose connector, poor earth, discharged battery, incorrectly adjusted pedal, broken operating spring or another electrical fault. Diagnose the circuit before replacing the switch.

Electrical return protection: Match the exact SKU and connector before installation or testing. Connected, installed, modified, damaged or used electrical parts cannot be treated as unused returns.

Technical Details

Installation Note

Professional installation is recommended because the switch must be mounted, connected and adjusted correctly for reliable brake-lamp operation.

During installation:

• Switch off the ignition before disconnecting the electrical connector
• Compare the old and new part numbers before connection
• Inspect the wiring and connector for corrosion, looseness or damaged terminals
• Install the switch in the original mounting position
• Use the correct model-specific operating spring
• Adjust the switch so the brake lamp turns on with normal rear pedal movement
• Ensure the lamp is off when the pedal is fully released
• Do not over-tighten the plastic switch body or adjustment nuts
• Secure the wiring away from the exhaust, chain, tyre and moving linkage

After fitting, test the rear brake lamp repeatedly with the ignition switched on. Confirm that the lamp illuminates promptly when the rear pedal is pressed and turns off every time the pedal is released. Also verify the front brake-light switch and complete tail-lamp operation before road use.
