Company Description
We are specialist distributors and suppliers of electrical switch components, including toggle, rocker, limit and proximity, safety and microswitches. We also supply inlets and connectors, control gear, timers, indicators, filters, relays, sensors, circuit breakers and fuseholders.

We have been in business for over 30 years, and we attribute our continual and successful growth to our commitment to providing an honest and traditional service, with experienced and dedicated staff. We maintain appropriate stock levels and computerised procedures in order to ensure a smooth-running operation.

We believe in keeping our promises to our customers, and we know that since business is conducted between people rather than between companies, we work hard to establish, maintain and build upon good relationships with our customers as well as our suppliers.

We are BSI Registered and Accredited to ISO 9001:2008 for the stockholding and supply of electrical switches and associated devices.
