The Bomag 05750565 Normally Open Switch is a genuine OEM electrical switch designed for Bomag tandem rollers and single drum rollers, including the BW 120 AD, BW 141 AD-2, BW 151 AD-2, BW 154 AD-2, BW 177 D-3, BW 213 D-3, BW 225 D-3, and the full range of BW-series machines listed in the fitment data. As a direct-sourced Bomag OEM component, this switch matches the original part in form, function, and electrical specification — so it drops into place without modification. This normally open switch covers an extensive lineup of Bomag tandem and single drum rollers across the -2 and -3 generation series, making it a dependable choice when you need an exact electrical match.
Key Features
- Genuine OEM Electrical Specification — sourced directly from Bomag, this switch meets the original circuit design requirements for correct normally open operation, ensuring the electrical system responds exactly as engineered
- Direct-Fit Replacement — engineered to match the original connector, mounting, and contact configuration on covered Bomag roller models, so installation is straightforward with no adaptation needed
- Broad Bomag Roller Coverage — fits an extensive range of Bomag tandem rollers including the BW 120 AD, BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, and BW 154 AD-2, as well as single drum rollers including the BW 177 D-3, BW 213 D-3, BW 213 DH-3, BW 216 D-3, BW 225 D-3, and many more BW-series variants
- Consistent Circuit Behavior — a correctly functioning normally open switch keeps machine control circuits operating as designed; a failed or incorrect switch can cause erratic electrical behavior, false signals, or loss of a controlled function
- Verified Part Number Traceability — ordering by Bomag part number 05750565 confirms you are receiving the exact switch specified in the OEM parts catalog for your machine
A normally open switch is an electrical switching element that sits in the open (non-conducting) state by default and closes the circuit only when actuated — by pressure, position, or mechanical contact. On heavy compaction equipment like Bomag rollers, these switches are used throughout the control and safety circuit architecture to monitor or trigger machine functions such as drum engagement, operator presence, or system interlocks. When a normally open switch fails — whether due to corrosion, mechanical wear, or electrical fatigue — the circuit it controls either stops responding or behaves unpredictably, which can disrupt machine operation or prevent the roller from functioning correctly. Replacing it with the correct OEM switch restores reliable, repeatable circuit behavior.
