Abstract (en)
[origin: EP0017819A1] 1. A low-voltage load switch having a safety fuse (hereinafter referred to as a fuse switch), the fuse link (6) of which is arranged under spring force between a head contact, which is additionally covered by a lid (5) which can be in the form of a screw cap (3), and a base contact (4), of a fuse mounting, and in the current supply to which is arranged a load switch (1) which is coupled to the lid (5) and which suddenly releases the contacts by way of a mechanism (14) in the form of a toggle lever, and which, without the fuse link (6), is locked in an open position, wherein ventilating channels ensure that the temperature of the connecting terminals does not exceed a given operating temperature, characterised in that a) a movable magazine (7) made of high temperature-resistant material is raised from the base contact (4) of the fuse mounting in the direction of the imaginary line (10) connecting it to the head contact under spring force (spring 9) with the screw cap (3) and the fuse link (6) removed, and that this base contact (4) maintains the fuse link (6) under pressure with respect to the screw cap (3) which, from the point of view of exchanging the fuse, retains the direction of the connection line (10) and thereby produces the contact force on the head contact and the base contact (4) of the fuse link (6), b) that the load switch (1) comprises a contact arrangement (contact members 12, 13) which is such that the imaginary line (11) connecting its contacts is inclined to the line (10) connecting the head contact and the base contact (4) of the fuse mounting, and that the lid (5) laterally prevents grasping of the screw cap (3), c) and that from the contacts of the load switch (1), a ventilating channel (53) leads past the magazine (7).
