The Wacker Neuson Trigger Switch is a genuine OEM component designed for the EHB 7 series electric demolition hammers, including the EHB 7M, EHB 7/115, and EHB 7/230 models. Sourced directly through Wacker Neuson's authorized parts program, this switch meets the original electrical specifications required for safe and consistent operation of these SDS-max rotary demolition hammers. Verify your model number against the fitment list before ordering to confirm compatibility with your specific unit.
Key Features
- Correct Electrical Rating: — Manufactured to the original switch specification, ensuring proper current handling and trigger response for the EHB 7 series hammer's motor circuit.
- Direct Drop-In Replacement: — Engineered to match the OEM connector and mounting configuration, allowing straightforward installation without modification to the tool housing.
- Broad EHB 7 Series Coverage: — Confirmed fitment across the EHB 7M, EHB 7/115, and EHB 7/230 electric demolition hammer models, covering both 115V and 230V variants.
- Restores Full Operator Control: — A worn or faulty trigger switch can cause intermittent power, unresponsive operation, or failure to start; replacing it restores crisp, predictable control over the hammer.
- Electrical Safety Compliance: — As a primary operator-contact electrical component, using the correct OEM-spec switch maintains the tool's intended circuit protection and reduces the risk of unintended activation or arcing.
The trigger switch is the primary on/off and power-control interface between the operator and the hammer's motor. When the operator squeezes the trigger, the switch completes the electrical circuit, sending current to the motor and initiating the hammering and rotation action. Over time, the internal contacts inside the switch can wear, corrode, or burn out from repeated use, leading to intermittent operation, a stuck-on condition, or a complete failure to start — all of which require the switch to be replaced before the tool can be used safely and reliably again.
