System M Switch

The range conforms to the standard 55mmx55mm backbox and accommodates multiple uses, including single and two-gang switches, temperature controls, data and electrical sockets and infrared receivers. The components for the standard Merten switch range was rationalised down from 3000 to 200 parts by creating families of interchangeable elements, improving supply chain efficiency. At the other end of the scale, BJD developed a glass switch programme for Merten, Trancent.
