Abstract
A push lock switch having a lock mechanism for use as a hazard switch or a rear defogger switch on an instrument panel of an automobile. The switch has first and second stationary members assembled together which define a space into which a movable member is slidably fitted. A push button fits over the movable member. A coil spring is mounted between the movable member and the first stationary member. The coil spring has first and second compression parts in a one piece construction with each other and urges the movable member toward the push button. A movable contacting strap is fixed to the movable member. The movable contacting member includes movable contacts and a retainer. The movable contacts slide into or out of contact with fixed contacts on the second stationary member when the movable member is pushed by the push button. The first stationary member has a bottom wall in which a recess is formed and on which a plurality of ribs are formed on the recess. A pin rises from the bottom wall of the recess to engage the engagement groove in a heart cam so as to pivotally support the heart cam. The heart cam is formed with a cam groove of a predetermined shape which is engaged with a lock pin inserted into the movable member, thereby providing a push lock mechanism.
