Ham radio operators use these connectors for 12 volt wiring. Really nice, a positive connection and the connector is hermaphroditic - they serve both as plug and socket so you only need one style of contact and one style of housing.
I was wiring some of them today to add a 12 volt connection to Buttercup the Tractor (for running a sprayer) and looked into the history of the company. Fascinating - they were founded in 1877
From Anderson Power Products:
CORPORATE HISTORY - 1877
Anderson Power Products began when the company converted an old brewery in downtown Boston into a foundry. One of the first projects was to cast various parts for the Boston Trolley Transit System. Product development and inventions such as the trolley pole, invented by Johan M. Anderson in 1890, put us on the map. The trolley pole was used in the overhead system of electric railways, providing a simple compact, efficient and durable supporting mechanism. APP received multiple awards for the Anderson brothers’ innovative trolley and railway designs.
There is another company whose products I use for grounding - ERICO - they are also an old company with a long history:
SERVING CUSTOMERS FOR OVER 100 YEARS
In 1903, the Electric Railway Improvement Company (ERICO) was created to supply power bonds, signal bonds and related welding equipment to railroads, mining and street railway industries. And for the next 112 years, the company expanded and flourished by adding capabilities and brands relevant to their core business as well as by promoting growth with forays into some new business arenas.
