Wacker Neuson 5100023402 Temperature Switch

The Wacker Neuson Temperature Switch is a genuine OEM component designed for a wide range of Wacker Neuson single drum soil compactors and tandem rollers, including the RC50, RC70, RC110, RD40-130, RD45-140, RD24-100, and RD28-120 series. As a direct OEM replacement, this switch is sourced from Wacker Neuson and built to the same specification as the original part fitted at the factory. Compatibility spans an extensive lineup of RC and RD series machines — including DPF, CAB, ROPS, and VO variants — making the a high-demand service part across mixed fleets. Confirm your model number before ordering to ensure a correct match from the fitment list.

Key Features

• Correct Thermal Trigger Threshold — Genuine OEM construction ensures the switch opens and closes at the precise temperature ratings the machine's cooling and engine protection system requires.
• Direct Drop-In Replacement — Engineered to match the original mounting thread, connector, and form factor for a straightforward installation with no adapting or reworking.
• Broad Fleet Coverage — Fits RC50, RC50p, RC70, RC70p, RC70vo, RC110, RC110p, RD24-100, RD28-120, RD40-130, and RD45-140 series machines, including DPF, CAB, ROPS, and US-market variants.
• Engine Overheating Protection — A correctly functioning temperature switch triggers the appropriate warning or shutdown response before heat damage can occur to critical engine components.
• Safety-Critical Electrical Component — This switch is part of the machine's thermal protection circuit; using a genuine OEM part ensures the trip point meets Wacker Neuson's design tolerances for reliable overheat detection.
• Genuine Wacker Neuson OEM Part — Supplied under part number 5100023402, sourced directly through the Wacker Neuson parts network for full traceability.

A temperature switch monitors coolant or engine oil temperature and sends a signal — or breaks a circuit — when a defined thermal threshold is reached. On compaction equipment like Wacker Neuson rollers and soil compactors, this triggers a dashboard warning light or initiates a protective engine shutdown, preventing catastrophic overheating damage during heavy compaction work. When the switch fails, the machine may either lose its overheat warning entirely — leaving the engine exposed to heat damage without any alert — or trigger false shutdowns that interrupt operation. Replacing a faulty temperature switch promptly restores the integrity of the machine's thermal protection system.
