Ignition switch assembly for a gas valve

An ignition switch assembly connectable to a shaft of a gas tap of a cooking device comprising:

• a coupling element adapted to be connected and rotated by the shaft of the gas tap, the coupling element having a base with a curved groove disposed therein,
• a cam having an eccentric peripheral surface and an eccentric hole, the eccentric peripheral surface having a protrusion extending radially from a portion thereof, the coupling element fitted within the eccentric hole such that rotation of the coupling element causes rotational and lateral movement of the eccentric peripheral surface of the cam, the cam having a guide fitted within the curved groove of the base that guides the lateral movement of the cam in relation to the coupling element,
• a fixed contact fixed in relation to the cam:
• and
• a mobile contact engageable with the eccentric peripheral surface of the cam and moveable between a contact relationship and a non-contact relationship with the fixed contact,
• the coupling element, the curved groove, the eccentric peripheral surface, the eccentric hole, the guide, the protrusion, the fixed contact and the mobile contact being situated relative to one another and configured such that when the coupling element is in an initial position the mobile and fixed contacts are in the non-contact relationship and wherein a first rotation of the coupling element in a first direction causes the mobile contact to engage with the protrusion of the cam to cause the mobile and fixed contacts to be in the contact relationship and wherein further rotation of the coupling element in the first direction beyond the first rotation causes the mobile contact to disengage with the protrusion to cause the mobile and fixed contacts to be in the non-contact relationship and wherein a subsequent rotation of the coupling element in a second direction opposite the first direction back to the initial position causes the mobile and fixed contacts to be in the non-contact relationship during the entire subsequent rotation.
