Detail of an old telephone switchboard from Darby, Montana. From the description, it sounds like the machine was in use until 1956.

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.
I think a switch is science because of how the wires all connect. I wonder how we can just flick the switch and the light can turn on?

This is the switch mounted on my '72 Commando (my K&N filter just below it was removed for the picture). On my bike this was a convenient location because I do not use the stock Dzus fastener to hold the sidecover on (largely because I don't have the stock sidecover).
Therefore, the hole for the Dzus fastener has remained empty, with just a rubber grommet in it. I cut that off (after 46 years it it was as hard as a rock) and used the hole to mount a metal plate that holds the switch.
This works well, but I plan to make a slightly longer plate to move the switch down and make it a bit easier to find with gloves on. As I said earlier, you MUST move the switch to the down position when the engine starts.

Detail pics of Switch Dojin. Also my first attempt with airbrush blushing. Obviously I need lots of work, but I never would have gotten the soft gray/silver eyebrows wanted by the client without it!! :D

Jack doing a switch polejam at a spot in Beverley. Shot with a Sigma 10-20 borrowed from college. I could do to get myself a tokina. This lens has pretty horrible distortion. And gives people massive hands.

This push-button light switch is in the hallway outside my apartment. My landlord is repainting this hallway, so I’m afraid he might want to modernize the light switch...
The letters H&H are stamped on this switch, between the buttons. You can see it better in the side view below. That’s the Hart & Hegeman Manufacturing Company, of Hartford CT, which produced light switches under that name from 1890 to the late 1920s. By the end of that period, this type of switch had mostly been supplanted by the modern flip type. The building is from the mid 19th century, so this switch could be from anywhere in that range.
Notice that this wall is made of horsehair plaster and you can see the hairs sticking out of the cracked edges where the switch is installed. Horsehair plaster was the most common way to build interior walls until the 1920s or so, which is when drywall became common.
