FIELD: electrical engineering. ^ SUBSTANCE: the electric power switch has a body and a connecting bus with an arcing horn with a fastening shelf installed on it. The connecting bus passes through a hole of the rear panel of the body. For connection of the arcing horn to the connecting bus a boss is provided on the fastening shelf of the arcing horn, and a recess receiving the boss-on the connecting bus. The fasteners catch a jumper located on the lower side of the connecting bus. At pushing in of the connecting bus with the laid over arcing horn, its fastening shelf from above and from the side is overlapped by a bead positioned on the body. Thus, the fastening board becomes free of the fasteners. ^ EFFECT: simplified wiring of the connecting bus and arcing horn and improved accessibility of the fastener for the arcing horn. ^ 4 cl, 2 dwg |
