摘要:
A switch element (1) for actuating a setting parameter on an electronic microdevice, such as a hearing aid, is characterized by a rotary element (7) having peripherally at least three contact points (9), said contact points being connected to one another in electrically conductive fashion. Furthermore, the switch element has an elastically mounted reset element connected with the rotary element as well as at least two electric leader contacts (3, 5), which can be switched into electrically conducting contact by turning the rotary element via the contact points.
摘要:
A variable resistor has a substrate, an insulating film, a resistance element, a rotary assembly and a wiper. The substrate has a first terminal having an annular segment, a second terminal and a third terminal having a semi-circular segment disposed adjacent to the annular segment of the first terminal. The insulating film has a central hole corresponding to the annular segment and covers the second terminal and the semi-circular segment. The resistance element is mounted on the insulating film and contacts the second terminal and the distal end of the semi-circular segment through two gaps of the insulating film. The rotary assembly is mounted on the substrate. The wiper is rotated by the rotary assembly and has multiple contacts respectively contacting the resistance element and the annular segment. Therefore, The rotary assembly can be continuously rotated to prevent accidental breakage without short-circuiting.
