The Wacker Neuson Pressure Switch is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. Sourced directly from Wacker Neuson, this pressure switch meets the exact specifications of the original part installed at the factory. It is confirmed compatible with multiple machine configurations across the RD27-100 and RD27-120 series, making it a reliable choice for fleet operators and service technicians working with this roller family. Having the correct OEM part on hand keeps your machine operating within its designed hydraulic parameters and avoids the guesswork of sourcing a non-specified substitute.
Key Features
- Genuine OEM Pressure Sensing Accuracy — Manufactured to Wacker Neuson's exact switching threshold specifications, ensuring the hydraulic system responds correctly under real operating conditions.
- Direct Drop-In Replacement — Matches the original mounting configuration and electrical connections on RD27-100 and RD27-120 rollers, allowing straightforward installation without adaptation.
- Broad RD27 Series Coverage — Compatible across multiple build variants of the RD27-100 and RD27-120 hydrostatic vibratory rollers, covering a range of machine numbers within that series.
- Hydraulic System Integrity — A properly functioning pressure switch protects the hydrostatic drive system by signaling abnormal pressure conditions before they escalate into costly drivetrain damage.
- System Protection Compliance — On hydraulic and hydrostatic systems, a correctly specified pressure switch is a critical safety and protection component; using the OEM-specified part ensures the switch activates at the correct threshold to protect operators and equipment.
A pressure switch monitors hydraulic or hydrostatic circuit pressure and sends an electrical signal when pressure falls outside the acceptable operating range. On a hydrostatic vibratory roller like the RD27, the pressure switch plays a key role in protecting the drive circuit — triggering warnings or shutdowns when pressure drops or spikes beyond design limits. When the switch fails or sticks, the machine may lose its ability to detect hydraulic faults, leaving the drivetrain vulnerable to damage or creating unsafe operating conditions that go undetected by the operator.
