Abstract

A wall of a seat (10) surrounding a fuse (11) is provided with a first and second guiding slot (31, 30), adjacent to each other at a first end of the seat (10), and a third guiding slot (32) at a second end of the seat (10), all transversal to the seat axis. In the first guiding slot (31) an electrically conducting intermediate plate (22) and in the second guiding slot (30) a bow spring (21) and in the third guiding slot (32) a size controlling bow insert (23) are engagably inserted. In the state of closed contacts, the intermediate plate (22) electrically contacts the down conductor contact (14), which is, through an insulating partition (15), completely electrically insulated from the surroundings. The bow spring (21) is elastically spreadable on both ends. The improved fuse seat makes possible a simple replacement of fuses of various dimensions and prevents a dropping of the fuses out of a magazine, the down conductor contact, however, is completely protected against being touched.

Description

technical field

[0001] The present invention relates to an electrical switch including a fuse base, and more particularly to an electrical switch including a fuse base provided for mounting on a rod. Background technique

[0002] Known from the applicant's patent SI 9700256 is an electrical switch which also has a base for a protective device or a fuse arranged in its housing. The base is only suitable for one fuse size, for other fuse sizes the base must be replaced. Any manipulation of the fuse is complicated, or simply impossible, when the appliance switch is mounted in a horizontal position. Since the protection of the downstream conductor contacts is not sufficient to prevent access, the appliance switch becomes dangerous if, by mistake, the leading-in side and the downstream side are interchanged. Contents of the invention

[0003] Therefore, the technical problem to be solved by the present invention is how to improve the fuse base so that it can be matched to fus...
