Product information

Description

Replacement on/off switch designed for the TMM1250 hammer drill model. This electrical control component restores start and stop functionality of the hammer drill and is supplied as a compatible spare part for units that have a faulty or worn main switch. The switch is intended for straightforward replacement during maintenance or repair of the TMM1250 tool, providing the required interface between the user trigger and the drill's motor circuit.

Advantages

The switch provides direct mechanical and electrical compatibility with the TMM1250 hammer drill, enabling repair without modification to the tool housing or wiring harness when the original switch fails. Built for repeated actuation, it re-establishes reliable on/off control and helps extend the working life of the hammer drill by replacing only the defective component. The part is compact and designed to fit the original mounting points and connector arrangement of the referenced model.

Suitable for

  • Repairing a TMM1250 hammer drill with a non-functional on/off switch
  • Maintenance work to replace a worn or intermittently working trigger switch
  • Spare-parts inventory for tool service workshops handling TMM1250 units

Key specifications

  • Function: on/off (trigger) switch for hammer drill control
  • Compatibility: intended for use with the TMM1250 hammer drill model
  • Mounting: designed to fit original switch mounting points and housing cutouts of the specified model
  • Electrical contacts: rated for typical power-tool motor control currents (matching original switch specifications)
  • Actuation: manual trigger operation with return mechanism

How to use

Disconnect the hammer drill from the mains and remove any battery pack if applicable before beginning repair. Access the internal switch area by opening the drill housing according to the manufacturer's disassembly steps for the TMM1250. Note the wiring positions and connector orientation, then remove the faulty switch and install the replacement ensuring correct wiring connections and secure mounting. Reassemble the housing and perform a functional check to confirm reliable on/off operation before returning the tool to service.

Usage recommendations

Use only when the tool is powered off and disconnected from any power source. If you are not experienced with small electrical repairs, consider professional servicing to avoid damage to the tool or risk of electric shock. Inspect wiring insulation and connectors during replacement; repair or replace damaged wiring to maintain safe operation.
