The Wacker Neuson is a genuine OEM DPST Off/On Switch designed for the RD27-100 and RD27-120 series ride-on tandem rollers. Sourced directly from Wacker Neuson, this switch matches the original component specification and installs as a direct, drop-in replacement with no modifications to the wiring harness or mounting position. It is confirmed to fit across multiple RD27 configurations, including the RD27-100 Roller Pro T4F, RD27-120 Roller Pro T4F, and RD27 Pro Tandem Roller variants. Keeping an exact-match switch on hand means your machine is back in service quickly after a failed or damaged control component.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to Wacker Neuson's original contact rating and switching specification, ensuring correct circuit behavior in the RD27 control system.
- Direct Connector Match — Wiring terminals and mounting footprint match the original switch position on the RD27 control panel, allowing a straightforward swap without reworking the harness.
- Broad RD27 Series Coverage — Verified fitment across RD27-100 and RD27-120 tandem roller configurations, including Pro and T4F variants.
- Consistent Machine Control — A properly functioning DPST switch ensures both circuits switch simultaneously and reliably, maintaining operator control over critical machine functions.
- Electrical Safety Assurance — As a primary control switch, using a correctly rated OEM component helps prevent unintended circuit behavior that could compromise safe machine operation.
The DPST (Double Pole Single Throw) Off/On Switch controls two independent electrical circuits simultaneously with a single actuator, making it a core control component in the RD27 tandem roller's electrical system. When the switch is toggled, both poles open or close in unison, allowing the operator to engage or disengage paired functions with one action. A worn or failed switch can result in partial circuit engagement, unresponsive controls, or unpredictable machine behavior — making timely replacement essential for safe and consistent roller operation.
