Bomag 05762339 Normally Closed Switch

The Bomag 05762339 Normally Closed Switch is a genuine OEM electrical switch designed for Bomag single drum rollers and tandem rollers across a broad range of BW-series models. Sourced directly from Bomag, this switch matches the original component specification, ensuring proper circuit behavior right out of the box. It is confirmed to fit models including the BW 213 D-40, BW 213 PDH-40, BW 213 DH-40, BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 211 D-40, BW 212 D-40, BW 216 D-40, BW 218 D-40, BW 219 D-4, BW 219 PD-4, BW 214 D-4, BW 214 DHC-4, BW 213 D-4, BW 213 PD-4, BW 213 DHC-4, BW 213 PDHC-4, BW 213 PD-40, BW 212 PD-40, BW 213 PD-4, BW 211 PD-40, BW 211 PD-4, BW 211 PD-40, BW 216 D-4, BW 216 PD-4, BW 216 PDHC-4, BW 179 DHC-4, BW 177 DHC-4, BW 177 D-4, BW 177 PDHC-4, BW 177 D-40, C850D single drum rollers, and BW 115 AC-3, BW 115 AD-3, BW 115 AC-5, BW 131 AD-3, BW 131 AD-5, BW 131 ACW-3, and BW 131 ACW-5 tandem rollers. Using the correct OEM switch part number 05762339 eliminates guesswork and protects the integrity of your machine's electrical system.

Key Features

• Genuine OEM Electrical Specification — Engineered to Bomag's original contact rating and switching logic, ensuring the circuit opens and closes exactly as the machine's control system expects.
• Normally Closed Circuit Design — Maintains a closed electrical path at rest, which is critical for safety-interlock and monitoring functions where a loss of signal must trigger a machine response.
• Broad BW-Series Coverage — Fits a wide range of Bomag single drum rollers including BW 211, BW 212, BW 213, BW 214, BW 216, BW 177, BW 179, BW 218, BW 219, and C850D variants, as well as BW 115 and BW 131 tandem rollers.
• Direct OEM Replacement — Replaces the original switch with an identical plug-and-play component; connector, mounting, and switching characteristics match the factory-installed unit.
• Protects Electrical System Integrity — A worn or incorrect switch can cause false signals, unresponsive controls, or failure to trigger safety interlocks — this genuine component restores correct system behavior.
• Safety-Critical Fitment — Normally closed switches are frequently used in interlock and shutdown circuits; using the correct OEM part number 05762339 is essential for maintaining proper machine safety logic.

A normally closed switch is an electrical component that completes a circuit when it is in its resting, unpressed state — current flows until the switch is actuated, at which point the circuit opens. On Bomag single drum and tandem rollers, this type of switch is commonly used in safety-interlock systems, operator presence detection, and shutdown protection circuits, where the machine must respond immediately if the signal is interrupted. When this switch fails — whether through contact wear, corrosion, or mechanical damage — it can cause erratic control behavior, nuisance shutdowns, or, more critically, a failure to shut down when it should, making prompt replacement with a correctly specified component essential.
