Reversing switch

Abstract

The invention provides a reversing switch, comprising a switch body and input terminals and output terminals arranged in pairs on the switch body and independent of each other, each pair includes an input terminal and an output terminal, and is characterized in that one The input terminal is connected to or disconnected from an output terminal through a plurality of mutually independent reversing connectors, and the plurality of mutually independent reversing connectors are set to move synchronously. The reversing switch provided by the present invention adopts a plurality of mutually independent reversing connectors between the input terminal and the output terminal to realize the connection and disconnection between the input terminal and the output terminal, and increases the connection between the reversing connector and the input terminal or output terminal. The contact area between the terminals reduces the contact resistance and improves the current-carrying capacity of the reversing switch; at the same time, due to the increase in the number of contacts, the contact reliability can be guaranteed when the power is on, and the impact of shock and vibration on the switch performance can be effectively resisted. influences.

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...
