Electromechanical Relays

Kempston Controls stock a comprehensive selection of electromechanical relays suitable for a huge variety of applications. You will find latching and non-latching relays, monitoring relays, interface relays amongst others.

Relays are an electrical switch whose function is to turn on/off the current within an electric circuit. Relays operate much like a light switch, power is switched on and off when the switch lever is moved, the primary difference is that a relay is operated by an electrical supply as opposed to being physically pressed.

Relays have many different uses and are often utilised in situations where electrical isolation is necessary or when a circuit needs to be controlled with a low-power signal.

Kempston Controls, a leading supplier of electrical and electronic components, stocks an extensive range of relays from all the leading brands including  Eaton, Finder, Siemens, Omron, ABB, Lovato, General Electric and many more.

Give our dedicated sales team a call on +44 (0) 1933 411411 or use the contact form above to discuss your relay requirements.
