Abstract
An electrical switch mechanism comprising: a fixed
contact; a movable contact on a lever carrier, movable
between an inoperative position and an operative position
where the contacts engage, through an intermediate position;
a pivotable rocker carrying first bias means for urging the
lever carrier, the rocker being pivotable from a first rest
position where the first bias means can urge the lever
carrier into the inoperative position and a second position
where the bias means can urge the lever carrier into the
intermediate position; an actuator comprising a push button
which, when actuated, pivots the rocker between the first
position and the second position, and a latch which retains
the rocker in the second position upon release of the push
button, the arrangement being such that when the push button
is subsequently released, the first bias means urges the
lever carrier into the operative position.
