ABSTRACT:
Most prior-art switch inserts for rotary switches of a type including wiped segments and a switch wiper have a tall construction, and are unsuitable for carrying high current loads. In a switch insert of this invention, wiped segments (5) are arranged inside a plastic plate (8) so that they can be contacted from another side by a further switch wiper (9) having contacts (10) arranged in a mirror image of contacts (11) of a first switch wiper (7), with the further switch wiper (9) having positioning lugs (12) that extend through control recesses (13) of the first switch wiper (7) to accept a leaf spring (15) in a locking slot (14) thereof on the other side. The leaf spring supports itself by resiliently bracing on a surface of the first switch wiper (7) facing away from the contacts (11), and thereby loads the contacts (10, 11) of both switch wipers (7, 9) against the wiped segments (5). Generally switch inserts structured according to this invention provide an extremely flat construction. The doubled contact makes a higher current capacity possible.
