Advance Cab Ignition Switch Start

Advance Cab Ignition Switch Start

The Terex 11637 Cab Ignition Switch is an OEM replacement part used in the cab of Terex Advance front discharge mixer trucks. Designed primarily for pre-2005 models, this switch initiates the engine starting sequence and powers the vehicle's accessory circuits. It is fully interchangeable with the newer post-2005 style switch (part number 28039), though it lacks the anti-restart safety lockout feature found on the newer version. Replacing a worn or failing ignition switch restores reliable engine starting and prevents intermittent electrical issues during operation.
