I am buying a rotary switch, and I have found these terms:
2 x Off/(On)
and
2 x Off/On
Could you please explain me the difference?
edit:
example of a switch with Off/(On) specification
(originally from this page)

Usually positions in parenthesis are momentary positions.
So a switch that is Off/(On) is a single throw switch that is momentary switch. It will not stay in the on position, but will spring back to the off position. A switch that is Off/On will stay in either position.

Sounds like the first one's a SPDT spring-loaded single-side-stable OFF-momentary ON switch, while the second one is just a vanilla DPST ON-OFF switch.
