FIELD: electricity. ^ SUBSTANCE: switch comprises two sides fixed by screws, a handle installed between them on a roller rotating together with the handle, a fixing unit comprising a bearing, a ball with a spring and a stop. The bearing is installed on the axis, and the axis is fixed in sides. The spring is installed in the handle cavity and pushes the ball, which rests with its surface against the bearing and the side stop, fixing the handle position. Between the sides there are fixed contacts, and a bridge in the form of a ""-shaped plate with contacts is installed inside a cross beam. The cross beam is installed so that its one end is located on the axis of the handle located on a single straight line with the handle roller and the ball with the spring installed in the handle cavity, and its other end is located in slots between sides as capable of free sliding along guides. The bridge in the form of a ""-shaped plate with contacts is pressed with the spring to the cross beam. ^ EFFECT: elimination of cross beam warp, quick wear of contacts, higher switching capacity of a switch and reliability. ^ 2 dwg |
