The Wacker Neuson Ignition Switch Assembly With Key is a genuine OEM component designed for the RD25 and RD15 hydrostatic double drum vibratory rollers. Sourced directly from Wacker Neuson, this assembly includes the key and delivers an exact match to the original switch specification — no guesswork on compatibility. It is the correct replacement for operators and service technicians maintaining RD-series tandem rollers in the field or shop.
Key Features
- Genuine OEM Switching Specification — Meets the original electrical contact and keyed-position spec for the RD25 and RD15, ensuring correct start, run, and stop circuit behavior.
- Includes Matching Key — Supplied as a complete assembly with key, so the switch and key are paired from the factory — no sourcing a separate key or rekeying required.
- Direct Fit for RD-Series Tandem Rollers — Engineered for the RD25 and RD15 hydrostatic double drum vibratory rollers; mounts to the original switch position without modification to the wiring harness or panel.
- Protects Engine and Hydrostatic Systems — A properly functioning ignition switch delivers clean, reliable circuit control to the engine start and shutdown systems — a worn or faulty switch can cause intermittent no-start conditions or prevent clean engine shutdown, putting the machine at risk.
- Electrical Safety Compliance — As a keyed ignition component, correct switch function is essential to operator access control and safe machine shutdown — using a verified OEM replacement maintains the integrity of those circuits.
The ignition switch assembly is the primary operator interface for starting, running, and shutting down the machine's engine. On hydrostatic tandem rollers like the RD25 and RD15, the switch also ties into shutdown and safety circuits that protect the drivetrain and vibration systems. When the switch wears or fails internally, operators may experience intermittent starting issues, loss of key-position detent feel, or an inability to cut power cleanly — all of which interrupt compaction work and can leave the machine in an unsafe state.
