A pushbutton switch is provided comprising a leaf spring with slotted leaf ends for forming a double contact and a fixed contact arranged transversely in relation thereto. The slotted spring ends, in the direction of the leaf spring axis, are provided with groove-shaped stampings. This results in a point-shaped contact which migrates as a result of the bending of the leaf spring so that a high contact pressure is produced and a self-cleaning of the contacts is achieved.

In a pushbutton switch or pushbutton-actuated slide switch having a detent mechanism designed to have the shape of a heart cam, an individual latching and a mutual unlatching is made possible in that, according to the invention, the heart cam is provided with a further, center curved path for the unlatching (disengaging) purpose. Within this area of the position of the detent pin, the latching is accomplished by a cross slide which, during the off-switching process, can be pressed via a limit stop and by the detent pin into the unlatching (disengaging) position.
