The Bomag 434022340 Battery Disconnecting Switch is a genuine OEM component designed for Bomag BF-series pavers and BM-series cold milling machines. Sourced directly from Bomag, this switch delivers an exact match to the original part it replaces, ensuring correct electrical isolation with no guesswork on fitment. It is confirmed compatible across a wide range of Bomag pavers — including the BF 222 C, BF 223 C, BF 600 C, BF 600 P, BF 691 C, and BF 691 C-HSE — as well as the BM 1200/30, BM 1200/30-T3, BM 1300/30, and BM 1300/30-T3 cold milling machines. Ordering by part number 434022340 guarantees you receive the correct switch for your specific machine.
Key Features
- Genuine OEM Electrical Integrity — manufactured to Bomag's original specification, ensuring correct switching capacity and contact resistance for your machine's electrical system
- Direct Drop-In Replacement — engineered to match the original mounting configuration and wiring connections, so this switch installs cleanly without modification
- Broad Fitment Coverage — compatible with BF 222 C, BF 223 C, BF 600 C, BF 600 P, BF 691 C, and BF 691 C-HSE pavers, plus BM 1200/30 and BM 1300/30 cold milling machines, including T3 variants
- Full Battery Isolation When It Counts — a correctly functioning battery disconnecting switch lets operators fully cut power to the machine during service, storage, or emergency shutdown, protecting both personnel and onboard electronics
- Electrical Safety Compliance — maintaining a functioning battery disconnect is critical for safe servicing; using the correct OEM switch ensures the isolation function performs as the machine was designed to require
The battery disconnecting switch is the master cutoff between the machine's battery bank and its entire electrical system. When activated, it breaks the circuit completely, preventing parasitic drain during storage and allowing safe electrical work to be carried out on the machine without risk of accidental energization. A failed or worn disconnecting switch can prevent full power isolation, creating a safety hazard during maintenance and potentially causing electrical damage from uncontrolled current flow.
