Calculated at checkout

The Marmitek X10 One Load Lamp Dimmer Micro Module LMM31 is designed to fit behind a standard switch or momentary switch to control incandesent lighting in the range of 25 - 300W.

This module requires a neutral feed to it!


  • Suitable for 230V and low-voltage lighting with a transformer, including halogen lighting.
  • Remote control via the mains using Marmitek X-10 Commands and with one or more momentary switches. 
  • Switches and dims lighting circuits up to 300W. 
  • Can be used in combination with ‘designer’ switching material. 
  • Soft start and smooth dimming features, remembers the last dim setting. 
  • Makes your X-10 system invisible.
  • Can be regulated from 0% lighting to the desired dim setting.
  • The module is not suitable for dimming and controlling low-energy light bulbs and tube lighting. An Appliance module should be used for these devices. 
  • Phase and Neutral have to be available before the module can be installed. 
  • Small enough (43.25 x 47 x 18.9mm) to fit into a wall box behind a standard wall switch.
