Abstract

A snap switch is disclosed with a snap spring which is fastened on a carrier, carries at least one switch contact which connects it electrically to the carrier and has at least two arms which are reciprocally biased to form a closed system of forces in which at least one arm under compressive stress can be switched by the effect of an external driving force onto the snap spring between two switch positions in which it has different curvatures.
