ABSTRACT A SWITCH MECHANISM A switch mechanism for controlling operating procedures in a processing machine, comprising a housing made of plastics material and having surface means defining a plurality of aligning apertures and a plurality of contactless proximity switches each embedded in plastics material and for controlling individual operations, and wherein the switches are aligned with one another in said switch housing with sensor heads of the proximity switches extending through said apertures in a wall (sensor head wall) of the switch housing and the proximity switches being switchable for inductive switching pulses for a moving switching element, characterised in that two current- supplying bus-bars flank the sensor heads on either side and are located on the inside surface of the sensor head wall, in that two hollow contact rivets of electrically conductive material extend through each proximity switch in the direction (a - a) of the axis of the sensor heads and are locatable on the adjacent current-supplying bus-bar so as to establish contact, and in that a securing screw, which extends through the current-supplying bus-bar and is in threaded engagement with the sensor head wall, extends through each hollow rivet,
