Bomag 05762209 Normally Closed Switch

The Bomag 05762209 Normally Closed Switch is a genuine OEM electrical component designed for a broad range of Bomag tandem rollers, single drum rollers, pneumatic tyred rollers, refuse/landfill compactors, reversible vibratory plates, recyclers/stabilizers, and trench compactors. As a direct OEM replacement sourced from Bomag, this switch meets the exact electrical specifications required to keep your machine's control circuits functioning as intended. Compatible models include tandem rollers such as the BW 120 AD, BW 135 AD, BW 164 AD, and BW 202 AD-2; single drum rollers including the BW 213 D, BW 177 D-3, BW 145 DH-3, and BW 225 D-3; refuse/landfill compactors across the BC 570 RB, BC 671 RB, BC 772 RS, and BC 1172 RB families; as well as the BMP 851 trench compactor, BPH 80/65 S reversible vibratory plate, MPH 121 and MPH 122 recyclers/stabilizers, BW 24 R and C 560 B pneumatic tyred rollers, and HYPAC C-series single drum rollers including the C 815 C, C 825 C, and C 850 C.

Key Features

• Genuine OEM Electrical Accuracy — Correct contact rating, terminal configuration, and switching logic sourced directly from Bomag, ensuring the circuit behaves exactly as the machine's control system expects.
• Drop-In Replacement — Matches the original mounting footprint and connector interface, allowing straightforward installation without rework or adapter hardware.
• Exceptionally Wide Fitment Coverage — A single part number 05762209 covers tandem rollers, single drum rollers, pneumatic tyred rollers, refuse/landfill compactors, reversible vibratory plates, recyclers/stabilizers, and trench compactors across multiple Bomag generations, including BW-series, BC-series, BMP, BPH, MPH, and HYPAC C-series machines.
• Circuit Integrity Restored — A worn or failed normally closed switch can trigger false shutdowns, disable safety interlocks, or prevent the machine from starting; replacing it restores predictable, code-compliant operation.
• Safety-Critical Compliance — Normally closed switches are integral to interlock and shutdown circuits; using the correct OEM-spec component ensures these safety systems respond as designed under all operating conditions.

A normally closed switch maintains an active electrical connection in its default, unpressed state and opens the circuit when actuated. In heavy compaction equipment, these switches are commonly used in safety interlock systems, operator presence circuits, and shutdown logic — meaning the machine relies on a continuous signal that is only interrupted when a specific condition is triggered. When the switch fails by sticking open or losing continuity, control circuits can misread machine status, causing unexpected shutdowns, failed starts, or disabled safety functions. Replacing a faulty switch with the correct OEM part restores the precise switching behavior the machine's control system is calibrated to expect.
