Bomag 05973201 Temperature Switch

The Bomag 05973201 Temperature Switch is a genuine OEM component designed for Bomag tandem rollers, 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 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, and BW 154 AD-2. Sourced directly from Bomag, this temperature switch is manufactured to the exact specification of the original part — ensuring correct signal output, proper threshold activation, and a drop-in connection to the machine's existing wiring harness. Specifying part number 05973201 when ordering confirms you receive the correct switch for your machine's temperature monitoring circuit, avoiding compatibility guesswork.

Key Features

• Correct Threshold Activation — manufactured to the original switching specification so the temperature signal triggers at precisely the right point, protecting the machine's engine and hydraulic systems from heat-related damage
• Genuine OEM Construction — sourced directly from Bomag, this switch meets the same electrical resistance and output tolerances as the part it replaces, with no performance compromise
• Direct Plug-In Fitment — connects to the factory wiring harness without adapters or modifications, matching the original mounting configuration on Bomag tandem rollers
• Broad Tandem Roller Coverage — fits a wide range of Bomag tandem rollers including the BW 100, BW 115, BW 120, BW 125, BW 131, BW 135, BW 138, BW 141, BW 144, BW 151, and BW 154 series machines
• Electrical Safety Compliance — a correctly functioning temperature switch is essential for triggering warning systems and shutdowns before overheating causes engine or component failure; a faulty switch can allow critical temperatures to go undetected

A temperature switch monitors fluid or coolant temperature within the machine and sends a signal to the operator display or control system when a set threshold is reached. On Bomag tandem rollers, this switch plays a direct role in protecting the engine and hydraulic circuit from damage caused by overheating — triggering a warning light or shutdown response before temperatures become critical. When a temperature switch fails, the machine may operate without any overheating alert, leaving the engine or hydraulic system vulnerable to heat-related wear or sudden breakdown.
