    A switch whose contacts move independent of the speed the handle is operated at. think of an over the center toggle mechanism with springs, where you can't tease the contacts.
    Just because you can, doesn't mean you should.

      Are you are looking at motor disconnects in article 430? If so, I think a snap switch basically refers to a standard 15A or 20A light switch.

        I believe it's any switch that operates by the movement of a handle that operates a spring and rocker mechanism to change the position of the contacts.

        Examples of switches that are not snap switches are knife switches, rotary switches and many push button switches.

            Is a momentary contact decora switch considered a snap switch?

            The more I learn, the more I realize just how much I don't know.

                A knife switch is like the ones Dr. Fronkonsteen has on his control panel-- a large handle, and 2 (or more) metal bars that the handle moves to complete or break a circuit. You can also 'tease' the contact-- not quite breaking the connection, or not quite making the connection. Makes for lots of sparks and arcs!

                    That's why I said it.
                    knife switch was "the" switch until snap switch was invented.
