Royal Enfield Bullet 350 / Electra Right Handlebar Switch – Self Start AHO | UNO Minda SW-0666BV | 1040429/A Reference

Royal Enfield Bullet 350 / Electra Right Handlebar Switch – Self Start AHO

If you are searching for a Royal Enfield Bullet 350 right switch, Electra 350 self-start switch, RH handlebar switch, starter / kill switch or an economical replacement for the original Royal Enfield switch module, this is the UNO Minda SW-0666BV.

UNO Minda lists SW-0666BV as an RH electric-start AHO handlebar switch for Royal Enfield Bullet 350cc / Electra (Self Start). It uses a 4-pin red female coupler and is intended for the AHO-type electrical layout.

Brand: UNO Minda
UNO Minda Part Number: SW-0666BV
Position: Right Hand / RH
Application: Bullet 350 / Electra Self Start
Type: AHO right handlebar switch
Connector: 4-pin red female coupler
Royal Enfield OEM Cross-Reference: 1040429/A

Royal Enfield Original Part Number Cross-Reference

An older UNO Minda application catalogue directly cross-references SW-0666BV to Royal Enfield genuine part number 1040429/A – Switch Module RH.

This cross-reference is especially useful when searching by the original Royal Enfield spare number. However, a cross-reference does not mean every motorcycle that has ever used 1040429/A should automatically be treated as confirmed fitment for this aftermarket listing. For this UNO Minda product, guaranteed application should remain limited to the manufacturer's stated Bullet 350cc / Electra Self Start AHO application unless the old switch, connector and wiring are independently matched.

Important Difference: SW-0666BV vs SW-0666C-E01

Do not order only because both switches physically look similar. Match the connector and switch functions first.

Compatibility

Not for These Applications

• Bullet 350 Kick Start – UNO Minda lists a different RH switch, SW-0666BW.
• Classic 350 Reborn / new J-Series Bullet 350 – different-generation switchgear.
• Hunter 350 / Meteor 350 – different J-Series switch assemblies.
• Older manual-headlamp-switch motorcycles using the 8-pin SW-0666C-E01 type.
• Any motorcycle whose existing connector, pin count or control layout does not match.

What This Switch Does

• Right-side engine run / kill control
• Electric self-start control
• Designed for the AHO-era RH control layout
• Direct vehicle-specific wiring arrangement when the correct application and coupler are matched

Why Choose UNO Minda?

• Branded replacement: a much safer choice than an unidentified local switch when you want a budget-friendly non-Royal-Enfield-boxed replacement.
• Vehicle-specific catalogue application: SW-0666BV is specifically listed for Bullet 350cc / Electra Self Start.
• OEM cross-reference available: older UNO Minda documentation maps this switch to Royal Enfield reference 1040429/A.
• Correct AHO configuration: avoids buying the older 8-pin manual-light switch by mistake.
• Easy identification: part number, side, connector type and OE reference are all provided so buyers can compare before installation.

UNO Minda vs Royal Enfield Genuine

This product is UNO Minda branded aftermarket replacement stock. It is not a Royal Enfield Genuine Parts boxed product. If you specifically require Royal Enfield original packaging, search for genuine part reference 1040429/A and verify that number against your motorcycle.

The advantage of this UNO Minda option is that buyers looking for a branded replacement can identify the exact application and connector while usually paying less than many genuine/OEM-labelled alternatives.

BS4 / BS6 Note – Please Read Before Ordering

The current product box supplied with this stock is marked “RH-ES BS4 BS6 BULLT 350 / ELECTRA”. UNO Minda's BS4/BS6 switch catalogue specifically places SW-0666BV under its BS4 Royal Enfield section, while the broader current catalogue continues to list the application as Bullet 350cc / Electra Self Start.

For this reason, BS6 should not be selected only by model name or emission stage. For a BS6-era UCE motorcycle, compare the old switch and confirm the same 4-pin red female coupler before purchase.

Before Ordering – 5-Point Check

1. Your motorcycle is a Royal Enfield Bullet 350 or Electra 350 UCE.
2. It is the electric / self-start version.
3. You need the right-hand (RH) switch.
4. Your old switch uses the same AHO control layout.
5. Your wiring ends in the same 4-pin red female coupler.

If available, also compare the motorcycle's original switch reference with 1040429/A.

Electrical Spare Installation Note

Professional installation is recommended. Disconnect the battery before electrical work. Do not cut or modify the coupler simply to make a mismatched switch fit. Test the starter and engine run/kill functions before completing final assembly.

Electrical Spare Return Policy

Electrical parts are non-returnable once connected, installed, plugged in, tested or used. Please compare the part number, application, side, switch layout and connector before ordering. Wrong/damaged-item claims require an unboxing video as per store policy.

Frequently Asked Questions

Is this a Royal Enfield genuine switch?
No. This listing is for an UNO Minda SW-0666BV branded replacement. It is not supplied as a Royal Enfield Genuine Parts boxed item.

What is the Royal Enfield original part number reference?
UNO Minda's earlier application material cross-references SW-0666BV with Royal Enfield 1040429/A – Switch Module RH.

Will this fit Bullet 350 BS4 self start?
Yes, Bullet 350cc Self Start BS4 is directly listed by UNO Minda for SW-0666BV, provided the motorcycle uses the matching AHO layout and 4-pin red connector.

Will this fit Electra 350 self start?
Yes, Electra Self Start is a manufacturer-listed application. Match the 4-pin red coupler before purchase.

Will this fit Bullet 350 kick start?
No. UNO Minda specifies a different RH AHO switch, SW-0666BW, for Bullet 350 kick-start applications.

Will it fit BS6?
The current retail packaging is marked BS4 / BS6, but manufacturer catalogue history identifies SW-0666BV primarily with the BS4 Bullet 350 / Electra Self Start AHO application. On a BS6-era UCE bike, order only after matching the existing 4-pin connector and switch layout.

Is this the same as SW-0666C-E01?
No. SW-0666C-E01 is an older manual-light-control RH switch using an 8-pin red female coupler. SW-0666BV is the AHO self-start version using a 4-pin red female coupler.

Can I buy it for Classic 350 just because 1040429/A may appear in some Royal Enfield catalogues?
Do not assume so. The OE cross-reference is useful for identification, but UNO Minda's verified SW-0666BV application is Bullet 350cc / Electra Self Start. Wider fitment should only be accepted after exact switch and connector verification.
