Founded in 1929, Hugo-Muller began as a manufacturer of speakers and a short while later OMEGA headphones and radios. In the decades that followed the business went on to produce analogue Time Switches and the first fully-electronic Time Switches variants amongst other capable products.

Today, Muller is still a family ran business and continue to make advances in automation and process control, product design and manufacturing. Their product range includes Digital Time Switches, Elapsed Time Counters, Shutter controls and much more.
