Product Description

The Two Wire One Load Lamp Dimmer Micro Module 2265D (Also known as LMM21) is an extremely small X10 module (43.25mm x 47 mm x 21mm) which can be fitted behind an existing wall switch. The lights connected to the MicroModule can be controlled by a X10 signal or by the switch in the normal way. The benefit of this Micromodule is that it only requires 2 wires to the switch and it can be connected to a normal light switch.


  • Suitable for 230V lighting - must be dimmable (not suitable for low energy loads)
  • Remote control via the mains using Marmitek X-10 Commands and with one or more standard or momentary switches. 
  • Switches and dims lighting circuits up to 300W. 
  • Can be used in combination with ‘designer’ switching material. 
  • Built-in powerline 'noise filter' and high X-10 signal sensitivity (25mV) 
  • Makes your X-10 system invisible.
  • No extra wires required for installation, works with a 2 wire switch.
  • Dimmer (60W - 300W).
  • Can be regulated from 0% lighting to the desired dim setting.
  • Transforms your existing switch into a X-10 controllable switch.
