An electrical switch is provided having at least one contact system having a switching contact movable between two switch positions, an operating member that acts on the switching contact, a slide hinged on the operating member, and delay means operatively connected to the switching contact in at least one of the two switch positions. The delay means delaying movement of the switching contact, and being arranged in an extension of the slide. The delay means, the operating member and the slide are arranged on a same side of the contact system.

Electric switch

Electrical switch

An electrical switch comprises, in addition to its switching mechanism or mechanisms, a potentiometer including a potentiometer plate and a slider which is advantageously moved/simultaneously with the actuation of the switching mechanisms. The switch requires terminal elements not only for the switching mechanism or mechanisms but also for this potentiometer. Consequently, an electrical connection must be provided within the switch between the inner ends of the terminal elements and the potentiometer plate. In accordance with the invention, the potentiometer plate is connected to the terminal elements by slip-in attachment which not only ensures a safe hold but also effects the electrical contact. To this end, the potentiometer plate is inserted into slot-shaped seats of the terminal elements, which are prevented from being unduly enlarged by suitable means. The firm hold is in addition ensured by corresponding grooves provided in the housing, and preferably and in addition, by studs which are provided on the housing cover and which, while securing the cover to the housing, are ultrasonically plasticized, in order to produce exactly fitting holding elements.
