Abstract: A microswitch includes a base (1), fixed contacts (2) and movable contacts (3). The movable contacts (3) are connected to a drive member (4) by way of a mechanism for switching the movable contacts having at least two assemblies (7) disposed in symmetry relative to the axis of the drive member (4). Each of the assemblies (7) includes a lever (8) and a spring (9) the outer ends (15,16) of which are interconnected to be capable of swinging angularly relative to each other. One element (8) of these two elements (8, 9) of the assemblies (7) is connected by its inner end (10) to the drive member (4) for swinging angularly relative thereto. Other respective elements (9) of each assembly (7) on which the movable contacts (3) are secured have the form of an integral resilient part (12) the central portion of which has secured thereto the movable contacts (3).

Abstract: A microswitch comprises stationary contacts (2,3) mounted on an insulating base (1), a four-link system (5) of levers which is made in the form of a chain including connected to each other in series an actuating link (8), two middle links one of which being a contact link (10) and the other one being an intermediate link (11) and a support link (9), and a limit stop (6) for holding one of the middle links (10 or 11) in the end positions. The actuating link (8) and the support link (9) being the end links are mounted for rocking on the insulating base (1), and one of the middle links, viz. the contact link (10) carries a movable contact alternately interacting with the stationary contacts (2,3). According to the invention, the movable contact (4) is located on the end of the contact link (10) connected with the intermediate link (11), and the limit stop (6) is located close to the place of connection of one of the middle links (10 or 11) with the support link (9).

Abstract: A microswitch comprises an insulating base, fixed contacts secured on the insulating base (1), a movable contact (4) adapted for selectively engaging the fixed contacts (2, 3) an actuating member (5), and means for shifting the movable contact (14) by the use of the actuating member (5). The means for shifting the movable contact (4) includes an actuating lever (6), an intermediate lever (7) a flat spring (8), and a contact lever (9) all connected in series with one another, the actuating and the contact levers (6and 9) being pivotally connected to the insulating base (1), the ends of the intermediate lever (7) and of the flat spring (8) being connected with one another a bearing up against a limit stop (17), and the contact lever (9) having a free end (12) whereon the movable contact (4) is located.
