Since the late 1920’s we have built countless motor starters, fitted and trusted by generations of contractors, while the increasing requirements of our markets have led us to constantly update and expand our ADS range to allow for an increased choice of current ratings and ingress protection.

This wealth of experience and expertise in the design and manufacture of Motor Control Gear is mirrored by our Heating and Lighting range which offers a versatile and comprehensive choice.

Although already offering a multitude of configurations and optional features, for those with particular requirements our Specials facility can cater for a variety of special purpose equipment including automatic changeover contactors and Stator-Rotor Starters.
