Abstract
Improvement in electric current switches, for low voltages, of the central rotary switch type manually operated by hand or button, characterized by a central rotary contactor with quadrangular section of insulating material provided on two opposite faces of conductive sheets electrically connected to each other or a fuse wire, the rotating contactor being attached to an external handle or control button in such a way that the assembly can be removed, extracting it from the box towards the outside, for the purpose of changing the fuse, without the need to disassemble the switch from the wall where is placed.
