Key Features
- Genuine OEM Electrical Specification — manufactured to Husqvarna's original switching specification, ensuring correct circuit engagement and consistent electrical response under load.
- Direct Plug-In Replacement — engineered to match the original connector configuration and mounting position, allowing straightforward installation without modification.
- Confirmed Fitment for Core Drill Models — compatible with the DM280, DMS280, and DM340 concrete core drills, covering both standalone drill motors and the combined DMS280 drill motor system.
- Restored Operator Control — a functioning switch delivers clean, reliable start/stop control; a worn or failed switch can cause intermittent power loss, failure to start, or unsafe unintended operation.
- Electrical Safety Compliance — using the correct OEM switch maintains the integrity of the machine's electrical control circuit, supporting safe operation on the jobsite.
The switch is the operator's primary electrical control point on a core drill, governing power delivery to the motor when starting and stopping the machine. When the switch degrades or fails, it can produce inconsistent motor engagement, unexpected shutdowns, or a complete loss of control — all of which interrupt drilling operations and create safety concerns. Replacing a faulty switch with a genuine OEM component restores proper circuit function and ensures the drill responds predictably to operator input.
