The Bomag 87270103 Rotary Switch is a genuine OEM rotary switch designed for Bomag BW-series tandem rollers and the MPH 121 recycler/stabilizer. Sourced directly from Bomag, this switch delivers the exact electrical specifications and physical fit your machine demands. Compatible models include the BW 184 AD, BW 170 AD, BW 174 AC, BW 174 AC AM, BW 174 AD, BW 174 AD AM, BW 180 AD, and MPH 121. When a rotary switch fails, critical operator controls can become unresponsive — replacing it with a genuine OEM component, part number 87270103, it restores proper system function and keeps your equipment operating to specification.
Key Features
- Genuine OEM Electrical Spec — matched to Bomag's exact resistance, contact rating, and switching sequence for reliable circuit control on these machines
- Drop-In Replacement — engineered to the original mounting pattern and connector interface, so this rotary switch installs directly without modification
- Broad Model Coverage — fits BW 184 AD, BW 170 AD, BW 174 AC, BW 174 AC AM, BW 174 AD, BW 174 AD AM, and BW 180 AD tandem rollers, as well as the MPH 121 recycler/stabilizer
- Restored Operator Control — a failed rotary switch can disable key machine functions; this genuine replacement brings full switching capability back to the operator station
- Electrical Safety Compliance — as a control-circuit component, using the correct OEM part ensures the switch meets Bomag's designed load and insulation ratings, reducing the risk of electrical faults
A rotary switch is an operator-facing control component that completes or interrupts specific electrical circuits when turned to a designated position. On Bomag tandem rollers and recycler/stabilizers, these switches manage functions such as vibration mode selection, lighting circuits, or auxiliary system activation. When a rotary switch wears or fails internally, the affected circuit loses response — operators may find a function stuck on, stuck off, or intermittently cutting out. Replacing the switch with genuine OEM part number 87270103 restores precise, predictable control and ensures the machine behaves exactly as Bomag designed it to.
