About us

Pennine Components Ltd were established in 1979 as a specialist distributor of Potter and Brumfield Relays and Saia Burgess Microswitches, and are located in the North of England some 25 miles east of Manchester.

Over the years the company has added many new suppliers and we continue with our theme of being specialists in the field of switching components such as Magnetic Switches, Safety Switches, Proximity Sensors and Relays to a wide variety of industry.

Initially we served the local UK oil, machine tool and bus fleet operator markets, however we now trade globally and are happy to accept enquiries from export customers and consumers too.

During 2010 the company recognised that many of our industrial customers were paying by credit card and we decided to merge our car parts accessory business Zackfords with our industrial components catalogue Pennine Components to create a single new website. The 2010 website gives customers of both brands enhanced search capabilities, more accurate information and the ability to place a credit card order for our entire product range. We aim to carry a wide selection from stock, and if its not in stock we will quote you a delivery time.

In september 2012 the company separated its custom electronics design and manufacturing activities into a new company called Switch Enterprise Ltd.All the products previously manufactured by Pennine Components are now available from the new company.

On the 24 April 2015 the company acquired the Greenbrook Controls and Components division of Greenbrook Electrical PLC. The business transfer took place on 1st of May 2015 where upon the 2 companies will merged to form a new distributor who will trade under the name Pennine Components Ltd Incorporating Greenbrook Controls & Components. Greenbrook Controls & Components was formerly known as B&R Relays.

In January 2021 the company completed another milestone and moved to a new purpose built warehouse at Canal Side Industrial Estate, Salford Way, Todmorden,OL14 7AJ,UK.  

In June 2021 the company upgraded its website to a new platform , providing live stock and pricing updates, and adding 17000 attributes with the aim of making product selection easier.

Whilst the website is new for 2021, we continue to offer our existing services:
