ABSTRACT:
A microswitch comprises a compression spring abutting onto an insulating base which supports conducting terminals, the spring exerting indirectly a permanent tension force on flexible lateral arms of a blade pivotably mounted on one of the terminals with its free end being movable between the other terminals. The tension force is exerted via a pivoting point on an oscillating lever guiding an applied control force and sliding on the insulating base by one of its ends which is opposite another of its ends which pivotably mounts the lateral arms of the blade and which applies the tension force of the compression spring thereto.
