Electrical switching device for controlling e.g. window regulator, of motor vehicle, has rapid contact break micro-switches configured to provide respective control knobs that are displaced vertically between rest and active positions

摘要

#CMT# #/CMT# The device has a slide (12) mounted movably in translation on a support, where the slide is displaced longitudinally with respect to the support in rest position and two active positions. Rapid contact break micro-switches (20, 22) has respective control knobs (24, 26) that are displaced vertically between the rest position and the respective active positions. The control knobs are maneuvered by co-operation with a cam profile (56) that is arranged on the slide so that the rest and active positions of the knobs depend on the positions of the slide. #CMT# : #/CMT# An independent claim is also included for a module comprising a connection unit. #CMT#USE : #/CMT# Used for controlling a window regulator or sunroof of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The rapid contact break micro-switches permit to obtain controlled and rapid switching during the translation of the slide using the cam profile in order to have less duration of electrical arc, thus preventing the electrical contacts from wear in an effective manner. The device is inexpensive. The configuration of the device permits to obtain perfect alignment of modules of the support and reduces the tolerance of positioning the modules of the support. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of an electrical switching device. 12 : Slide 20,22 : Micro-switches 24, 26 : Control knobs 56 : Cam profile 62, 63 : Walls.
