description

Part number: 803604677
Part name: selector switch
Unit name: electrical system
Fit for XCMG road roller XS135, suitable for rural road construction, subgrade backfill and small‑site compaction. Used to replace original selector switch with gear failure and poor contact.

Burned internal contact, spring fatigue and oxidized connector will cause gear failure, gear jumping and signal loss, making mode adjustment unavailable and disturbing on‑site compaction work.

====================================

advantages

Gear logic, mounting dimension and connector pin definition fully match original parts. Direct in‑cab replacement without modifying original wiring harness.
Wear‑resistant internal contacts withstand frequent gear operation, adapt to continuous site vibration and reduce virtual‑connection risk.
Dust‑proof and oil‑resistant housing prevents dust and mud intrusion, slows contact oxidation and ensures stable signal transmission.
Standard vulnerable cab electrical part with compact size for easy bulk stocking. Fast on‑site assembly cuts downtime and meets spare‑parts stocking demand of overseas projects in Southeast Asia and Africa.

maintenance & replacement

Disconnect main power supply before maintenance to avoid short‑circuit and burnout of controller and switch components.
Pull out connector gently instead of violent prying to prevent pin bending. Fasten switch bracket firmly during installation.
Insert connector fully in place and take protective measures to avoid terminal rust caused by mud infiltration.
Power on after installation, shift each gear sequentially and test corresponding functions such as vibration and speed adjustment.
Do not disassemble for reuse when contacts are burned or gear jumping occurs, replace selector switch directly.
