About Us

Capricorn Controls is a technically driven company and market leader in the design and manufacture of industrial electronic controls. Established in 1988, we invested in our first factory unit in 1991 and our current 3000sqft premises in 2000 from where all design and manufacturing is controlled. We remain a family run business and operate in partnership with our customers to provide the best service possible.


Product development is on-going, utilising proven technology in both new designs and refining existing lines to ensure continued reliability. All design and development is carried out in-house by our own engineers with many new products incorporating the latest in microprocessor technology. Investment in automated equipment, including wire cutting and stripping has expanded our engine harness and wiring loom business. The addition of a precision milling machine for circuit board drilling and isolation-routing enables rapid PCB prototyping.


Standard products include key start, remote start, start-on-demand, auto-transfer, mains-failure and mutual-standby controllers. Battery chargers, power supplies and battery backed DC systems. Relay assemblies, annunciators, timers and real time clocks. Frequency, speed, voltage, current and temperature monitors. We offer a wide range of accessories including key-switches, magnetic pick-ups and automotive relays. All popular 72mmsq modules are supplied in boxes injection moulded to our own design with a unique locking sleeve that is both easy to fit and remove – no more ‘fiddly’ clips.


Bespoke designs as well as customised products have become an important part of our business. We offer resin encapsulated circuitry for harsh environments with extremes of temperature, humidity and vibration. We design and manufactured for a wide range of industries including commercial, industrial and military projects.


Quality control and traceability are found throughout Capricorn Controls. No products of our own design are made obsolete; any item from 1988 to the present day can be re-manufactured to order. Full technical support is assured both before, and after sales and our longstanding clients have come to appreciate the direct access to engineers with hands-on experience.


Dispatching worldwide through an expanding distributor network, we have many satisfied customers in Europe, Africa, The Middle East, Far East, Australasia, South America, Canada and USA.
