Abstract

This invention relates to omnipotence switch, which comprises several layers of touch element with base socket, electrical probe, probe rack, probe spring, interface screw and protruding wheel and is characterized by the following: the base socket is located with step wheels located parallel on the socket center; there are two probe racks and tow probe racks of step symmetrically on outside and inside of the base socket; the two probes racks inner end is connected to the two protruding wheels; the outer end and the socket are located with one probe spring in between; there are two pairs of electrical probes not in one plane relatively to two probe rack and each pair of probes have two fixed electrical probes and one mobile electrical probes.

Description

Technical field: [0001] The invention relates to a universal transfer switch. It belongs to the electrical technology field. Background technique: [0002] Before the present invention was made, traditional universal changeover switch was made up of multilayer contact assembly and operating mechanism, fixing mechanism. Each layer of contact assembly of the universal transfer switch is composed of a base, an electrical contact assembly (two fixed electrical contacts combined with a movable electrical contact), a contact bracket, a contact spring, a wiring screw and a cam. The connection and disconnection of the movable electric contact and the fixed electric contact are realized by controlling the contact support on different track surfaces of the cam through the operating mechanism. Generally speaking, each layer of contact components has two pairs of electrical contacts, and the two pairs of electrical contacts are in the same plane, which mainly has the following disadva...
