The Multiquip 52012 Ignition Switch With Keys is a genuine OEM component designed for RAMMAX walk-behind and ride-on roller models including RW1403HF, RW1404, RW1404MR, RW1504HF, and P33/24 series equipment. As a factory-sourced part, the 52012 delivers the correct electrical connections, keyed positions, and switching logic that Multiquip rollers depend on for reliable engine starting and shutdown. This switch is a direct-fit replacement that installs into the same mounting location as the original, with no rework needed to the wiring harness or panel. Sourced through DHS Equipment, you can be confident you are receiving an authentic Multiquip part with the correct specifications for your machine.
Key Features
- Correct Keyed Configuration — Includes matching keys and delivers the precise ON/OFF/START switching positions required by Multiquip roller ignition circuits.
- Genuine OEM Sourcing — Factory-original part carrying the Multiquip part number 52012, ensuring correct terminal layout and contact rating for the roller electrical system.
- Broad Roller Fitment — Confirmed compatibility with RW1403HF, RW1404, RW1404MR, RW1504HF (up to S/N 1534188), and P33/24 FR/FC/FCR and HHMR-BD configurations.
- Restored Engine Control — A worn or failed ignition switch can prevent the roller from starting or cause unintended shutdowns mid-operation; replacing with part 52012 restores full operator control.
- Electrical Safety Compliance — An OEM-spec ignition switch maintains correct circuit isolation at each key position, preventing unintended cranking or energized circuits when the machine is switched off.
The ignition switch is the primary operator interface for starting, running, and shutting down the engine on your Multiquip roller. It routes power to the starter circuit when turned to the start position and cuts the ignition signal when turned off, bringing the engine to a safe stop. When the switch wears internally or the contacts corrode, operators may experience hard starts, intermittent engine cutouts, or a machine that will not shut down cleanly — all of which disrupt compaction work and create safety concerns on the jobsite.
