  • Switch-valve assembly having rotatable operating mechanism with latch
    Patent number: 4123633
    Abstract: A valve and switch assembly having a rotatably movable actuating mechanism in common. The actuating mechanism acts to actuate both devices when rotated. A latch mechanism, however, prevents rotation of the actuating mechanism when it is rotated to a first position. The latch is deactuated by axially depressing or collapsing the actuating mechanism and then rotating it. An additional unique feature lies in the switch assembly in which the switch contacts are electrically insulated from the actuating mechanism.
