Abstract

The invention discloses a circuit changing switch, and belongs to the technical field of circuit switches. The circuit changing switch comprises a switch body, a spring seat, contact springs, a spring, contacts and a pin, wherein stepped holes are formed in the side wall of the switch body, grooves are formed in the circumferential surface of the switch body, the contacts are installed in through holes of the grooves respectively, the spring seat is arranged in a hollow portion of the switch body, a plurality of grooves are formed in the outer circumferential surface of the spring seat, the contact springs are arranged in the grooves, a through hole is formed in the center of the spring seat, the spring is placed into the large-size end of the through hole, and the pin is arranged in the spring seat. The pin is pushed through external force to enable the spring seat to move in the stepped holes, so that the contact springs make contact with different contacts to form different connected loops, and switching between connection and disconnection of the circuit changing switch is accomplished. The circuit changing switch has the advantages of being large in number of changing channels, small in size, simple in structure and high in reliability.

Description

technical field [0001] The invention relates to the technical field of circuit switches, in particular to a multi-group travel switching switch, which is suitable for on-off switching of circuits and judgment and detection of original states of circuits. Background technique [0002] In the electromechanical field, the circuit transfer switch plays a pivotal role, because the reliability of the circuit transfer switch is related to the on-off of the circuit and the accuracy of the original state judgment and detection of the circuit, which is one of the important judgments for the safety of the circuit system. one. For this reason, a circuit transfer switch with many transfer channels, small size, simple structure and high reliability is a very important research topic in the current circuit switch technology field. [0003] Existing circuit transfer switches such as figure 1 shown. The circuit changeover switch has a cuboid structure and includes a switch body, a spring ...
