The contactors in a battery pack need to be able to switch high currents and high DC voltages. Hence they tend to be specialised discrete components. The following is a list of contactor manufacturers
Albright International
A privately owned company founded in 1946 which has been successfully operated by three family generations. Commencing with the manufacture of the Albright contactor range in the 1950s, the strong tradition of designing and manufacturing our own products continues to this day. Albright is proud to be one of only a few contactor companies that wholly designs and manufactures its own product ranges.
Albright International operates from our Head Office at Whitchurch in the South of England, which incorporates a wholly owned manufacturing facility and Sales Office.
