Embodiment Construction

[0032] The present invention is described in further detail below in conjunction with accompanying drawing:

[0033] figure 1 It is the block diagram principle of the present invention

[0034] The present invention is made up of one-way stop trigger 7, two-way operation driver 12, two-way control trigger 18 or 26, magnetic latching relay K1, K2 etc. composition. The power live wire input terminal 2, positive and negative start control terminal 3, stop control terminal 4, forward and reverse output terminals 5 and 6 of the five-terminal three-wire positive and negative stop three-state multi-way control switch 1 are connected externally, so It is called a five-terminal control switch, and it is composed of three lines of power zero line, positive and negative start control terminal 3, and stop control terminal 4. Therefore, it is called a three-wire system multi-channel control switch. The three-state control of forward rotation, reverse rotation and stop is realized through...

Abstract

A five-end, three-line system positive, negative and stop three state multi-channel control switch is composed of two kinds of magnet keep relays, a two-way control trigger, a single-way stop trigger and a two-way operation driver. The power supply input end is connected with the supply live wire, positive and negative ends of the switch are connected with the positive and negative connectors of the motor, the stop control end is connected with the zero line via a button, the start control end is connected with two buttons by two diodes in different directions, the other end of which is connected with the supply zero line so as to control on the three lines.

Description

Technical field: [0001] The invention relates to the field of low-voltage switches and is suitable for low-voltage control circuits below 500V. Background technique: [0002] The current positive and negative stop three-state multi-channel control switch can only be completed through many complicated control lines and special switches, which wastes materials and is extremely inconvenient to install and use. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a five-terminal three-wire motor with simple structure, low cost, fewer control lines, three-wire motor forward rotation, reverse rotation, and stop three-state control, and multi-channel control Control positive and negative stop three-state multi-way control switch. [0004] The purpose of the present invention is to be achieved through the following technical solutions: [0005] The five terminals mentioned in the present invention refer to ...
