UK101 Keyboard Switch: Underside
These keyboard switches are one of the unique parts of the Compukit UK101. In the early 1980s, they were available from RS Components and from a supplier called Devlin. They are taller than typical keyboard switches available today. I'd like to find a supplier where I can buy spares in small quantities today. The only markings on the switches are "MEI" and "WEAB". The body of the switch is 15.7mm square and 17.6mm tall. The stem is 9.3mm long and has 4.5mm of travel. The cruciform fitting for the keytop is 4.75mm wide and the arms of the cross are 1.2mm thick. There are two plastic locating pegs on the bottom of the switch, 2.3mm diameter. The pin connections are 1.2mm diameter, 5.4mm pitch.
UPDATE: I've now found a brochure from a manufacturer called "Mechanical Enterprises, Inc.", who made these switches.
