But are they of a major name brand?

Leviton, if I remember correctly.

...

There is a strap with up to 3 rectangular holes and a couple tabs. This
becomes the yoke for a device assembly by inserting small separate devices
into each. They look like the duplex receptacle, except 3 holes instead
of 2, and smaller. Sides were rounded and the top and bottom were straight.

OK, I think I've seen these before, in an old house in Buffalo I lived
in.

I just had a need for 3 switches in a device, to switch the 3 components
of a bathroom light/fan/heater. I put in a Decora switch despite that
I dislike them. (what faceplate does a triple Despard switch take?)

A triple despard switchplate. Until Decora came out with a triple rocker switch
which fit into a single faceplate, a triple despard switch and faceplace.
factory labeled Heat / Vent / Light was included with every new HVL sold.

Speaking of multiple things in a device, I vaguely remember a kitchen
outlet in a summer cottage our family had. There were 5 outlets in the
single box device. (obviously no ground prong)
