  • the slider 303 When the switching element 300 is actuated, the slider 303 is adjusted linearly in the housing part 200. Due to the gear formed between the slider 300 and the regulator 400 with the actuator 106,107,109 and the actuator receptacles 305, 306, the linear movement of the slider 303 outside the contact space 208th converted into a rotary motion of the regulator 400. When the controller 400 rotates, so are the controller 400, the control contacts 30 are rotated on the circuit board 10, whereby the ohmic resistance can be adjusted.
  • the actuating part 60 With the actuating part 60, three switching stages can be realized. In an intermediate switching stage, the two contact elements 40 are not electrically connected to each other. As a result, an off position is realized. Starting from this middle switching stage, the actuating member 60 can be rotated in both directions become. Upon rotation of the actuating part 60, the rotatably connected positioning element 500 is rotated in the contact space 218. The rotation is effected by means of the spring 20, which is in the individual switching stages with their holding elements 23 in the positioning receptacles 509. With the rotation of the positioning member 500 and the contact elements 40 are rotated. In the switching stages represented, the contact elements 40 are electrically conductively connected to one another via the printed circuit board 10, as a result of which an anticlockwise or clockwise position can be achieved.

Abstract

L'invention concerne un commutateur pour un appareil électrique, en particulier pour un outil électrique, comprenant un régulateur (400) servant à régler la vitesse de rotation de l'appareil électrique. Une carte de circuits imprimés (10) est disposée dans un espace de contact (218) d'un boîtier de commutateur. Le régulateur (400) repose par des contacts de réglage (30) dans l'espace de contact (218) sur des pistes conductrices de la carte de circuits imprimés (10). Le régulateur (400) peut être actionné au moyen d'un coulisseau (300). L'invention vise à réaliser un commutateur de ce type présentant une étanchéité importante par rapport aux infiltrations de poussières. L'invention prévoit à cet effet que le régulateur (400) est monté de manière rotative et le déplacement par glissement du coulisseau (303) est transformé au moyen d'un engrenage en un déplacement par rotation du régulateur (400), et que le coulisseau (303) est maintenu et guidé à l'extérieur de l'espace de contact (218).
