A switch is an electrical control component that opens or closes a circuit in response to operator input, sending the signal needed to activate or deactivate a specific machine function. On Bomag BW-series rollers, switches govern key operational controls, and a worn or failed switch can result in unresponsive functions, false readings, or intermittent behavior that disrupts compaction work. Replacing a faulty switch with part number 32121356 restores clean electrical contact and consistent control response, keeping the roller performing as designed.
