1951Manchester Mark 1: console switches stay put in either position, and one decides whether an instruction stops the machine. Turing's handbook, Manchester.
See also: IBM 701 sense switches, 1953.
“'switches' are stable in either position, whereas 'keys' must be kept pressed ... For each of the instructions /L and /G there is a switch deciding whether that instruction shall be a `waste time' or a stop.”
Turing's handbook draws the line: a switch stays where you put it, a key must be held. The Spacewar! switches the table had were held, which is Hold.
