Abstract
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.
