WAGO: 75 years of connectors

[RobertArthur]

WAGO, founded April 27, 1951. A timeline of their innovations on this website. Sweet memories: a French électricien who insisted time and again that Wago connectors were not permitted, because they were not ‘NF’ approved. The times they're changing: there is also a party going on in Paris, near Charles-de-Gaulle airport.

Having a few minutes spare while watching the UK Local Election results I visited the WAGO link you supplied. The modern connectors are superb and remind me of the limited variety available in the 60/70s including the pcb mounted range.
By the way, what replaced “Plessey plugs” that we relied on for all our development work?
