What it is

The WMDR1L is a Hager Sollysta 1-gang rotary dimmer switch with leading-edge dimming, rated at 400W. It has a rotary control for dimming with a quick press to switch the light on or off, and is suitable for mains halogen lamps without needing to derate, as well as many dimmable LED lamps and fittings.

Signs this part needs replacing

  • Light flickers, buzzes, or fails to dim smoothly
  • Rotary control feels loose, sticks, or won't turn
  • Switch fails to turn the light on or off
  • Visible scorching, discolouration, or a burning smell around the switch

Before you order

  • Isolate the lighting circuit at the consumer unit before removing the old switch
  • Match the exact part number printed on the existing switch
  • Check your lamp load and type (halogen/LED) is within the dimmer's 400W rating and compatibility
