Bomag 05973202 Temperature Switch

The Bomag 05973202 Temperature Switch is a genuine OEM component designed for Bomag BW-series tandem rollers and the MPH 600 recycler/stabilizer. Sourced directly from Bomag, this switch carries the exact specifications required for a correct, drop-in installation. It is confirmed to fit a wide range of Bomag tandem roller models, including the BW 100 AC-3, BW 100 AD-3, BW 115 AC-3, BW 115 AD-3, BW 120 AC-3, BW 120 AD-3, BW 125 ACH, BW 125 ADH, BW 131 ACW-2, BW 131 ACW-3, BW 131 AD-2, BW 131 AD-3, BW 135 AC, BW 135 AD, BW 138 AC, BW 138 AD, BW 138-AD, and BW 71 EHB-2, as well as the MPH 600 recycler/stabilizer. When a temperature switch fails, it can leave critical thermal protection systems unmonitored — replacing it with an authentic Bomag part number 05973202 ensures the machine responds correctly to temperature conditions and protects the engine and hydraulic systems from heat-related damage.

Key Features

• Authentic OEM Switching Threshold — calibrated to Bomag's exact activation temperature, so the switch opens and closes at the correct set point rather than drifting out of tolerance like a worn or mismatched part
• Direct Connector Match — terminal configuration and thread spec match the original mounting point exactly, allowing straightforward installation without adapters or wiring modifications
• Broad Tandem Roller Coverage — fits the full BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, and BW 138 tandem roller lines, plus the BW 71 EHB-2 walk-behind/light roller and the MPH 600 recycler/stabilizer
• Engine and Hydraulic Protection — a correctly functioning temperature switch triggers warnings or shutdowns before heat damage occurs; a faulty switch can allow overheating to go undetected, leading to costly internal damage
• Electrical Safety Compliance — as a protective sensing component in the machine's thermal management circuit, using the correct OEM switch ensures the safety system operates within Bomag's designed parameters

A temperature switch is a sensing device that monitors fluid or component temperatures within the machine and signals the control system when a defined threshold is reached. On tandem rollers and recycler/stabilizers, this typically protects the engine coolant circuit or hydraulic system by triggering a warning light or initiating a protective shutdown before heat reaches a damaging level. When the switch fails — either stuck open or stuck closed — the operator loses accurate thermal feedback, leaving the machine vulnerable to undetected overheating or unnecessary fault warnings that interrupt work.
