Reversing switch

Abstract

The invention provides a reversing switch which comprises a switch body, input terminals and output terminals. The input terminals and the output terminals which are independent from one another are arranged on the switch body pairwise, and each pair comprises one input terminal and one corresponding output terminal. The reversing switch is characterized in that each input terminal is connected with the corresponding output terminal by a plurality of mutually independent reversing connectors or disconnected from the corresponding output terminal via the mutually independent reversing connectors, and the mutually independent reversing connectors can synchronously move. The reversing switch has the advantages that the input terminals can be connected with the output terminals by the multiple mutually independent reversing connectors and can be disconnected from the output terminals via the multiple mutually independent reversing connectors, so that contact areas among the reversing connectors and the input terminals or the output terminals can be increased, contact resistance is reduced, and the current carrying capacity of the reversing switch is improved; as contacts are increased, the contact reliability can be guaranteed when the reversing switch is electrified and works, and the influence of impact and vibration on the performance of the switch is effectively eliminated.

Description

technical field

[0001] The invention relates to the technical field of electrical system switches, in particular to a reversing switch. Background technique

[0002] At present, the forward and reverse mechanisms used in the reversing switches on the market are basically divided into two types:

[0003] The first category, electronic forward and reverse mechanisms: realize the forward and reverse functions of the motor (motor) through electronic circuit connection;

[0004] The second category, mechanical forward and reverse: realize the forward and reverse functions of the motor (motor) through mechanical structure connection;

[0005] The former is rarely used because of its high cost; the latter is widely used because of its low cost and easy implementation.

[0006] Among them, the mechanical forward and reverse mechanism also includes the side contact type: relative to the working parts of the forward and reverse connecting parts, the corresponding working parts of th...
