XCMG XCT25K Crane Ignition Switch
This ignition switch is intended for compatible XCMG XCT25K crane carrier electrical systems. It distributes battery power to the specified key positions and starting circuit. Terminal layout and switch stages must match the original unit.
Identification and Matching
XCT25K serial number and production year
Original switch label or part number
Number and marking of key positions
Terminal count, arrangement and connector type
Barrel diameter, mounting thread and supplied key set
Application and Service Scenarios
Replacement may be required when contacts are confirmed open or high resistance, the key mechanism binds, the return-from-start function fails or the housing is damaged. No-start symptoms may instead come from batteries, fuses, neutral interlocks, relays, wiring or the starter circuit.
Inspection and Installation
Isolate battery power, label wires and compare each terminal designation. Secure the switch without twisting the harness. After installation verify OFF, accessory, ON and START functions, key return and relevant safety interlocks.
Frequently Asked Questions
Can any four-position switch be substituted?
No. Terminal functions, current path and mounting must match.
Does a no-crank condition prove the switch is bad?
No. Test the starting circuit and interlocks first.
Should the old key be reused?
Use the key supplied for the matched switch unless the service solution specifies otherwise.
Export Packing
The key barrel and terminals are capped and protected from impact and moisture in labelled packaging.
