Abstract
An ignition switch assembly connectable to a rotary shaft of a gas tap of a cooking device. The ignition switch assembly has a coupling element connectable to the rotary shaft of the gas tap, a fixed contact, a mobile contact, and a cam coupled to the coupling element which is configured to move the mobile contact relative to the fixed contact. The cam has a guide that is moveable within a groove of the switch assembly which controls the lateral displacement of the cam in relation to the coupling element so that the lateral displacement of the cam is controlled such that when the coupling element is rotated in a first direction, electrical contact between the mobile and fixed contacts is achievable, but when the coupling element is rotated in a second direction opposite the first direction the lateral displacement of the cam is controlled to prevent electrical contact between the mobile and fixed contacts.
