Multi-switch controller

Abstract

The invention relates to a multi-switch controller, which comprises a power supply circuit, a switch control circuit and a load circuit, wherein the switch control circuit comprises switching groups from K1 to KN connected with one another; each switching group consists of an elastic switch S1, an elastic switch S2 and an elastic switch S3; two ends of the elastic switch S1 in each switching group are connected with a conducting wire a and a conducting wire b, two ends of the elastic switch S2 in each switching group are connected with the conducting wire b and a conducting wire c, and two ends of the elastic switch S3 in each switching group are connected with the conducting wire b and a conducting wire d; a normally open contact A1 is connected between the conducting wire a and the conducting wire b, and a normally open contact A2 is connected between the conducting wire b and the conducting wire c; the terminal point of the normally open contact A2 connected with the conducting wire b is a power supply terminal point E; a normally closed contact A4 and a coil L1 are connected between the conducting wire a and a conducting wire e, and a normally closed contact A3 and a coil L2 are connected between the conducting wire c and a conducting wire e, and a coil L3 is connected between the conducting wire d and a conducting wire e; and the conducting wire e is connected with a power supply terminal point G through a normally closed contact A5. The multi-switch controller achieves the function that a plurality of switches conveniently control one load or control a plurality of operation functions of loads.

Description

technical field [0001] The present invention relates to switch controllers, and more particularly to a plurality of switch controllers. Background technique [0002] At present, when the existing switches are used to control load devices such as lamps, motors, heaters or industrial driving devices, single-switch control devices are generally used, and at the same time, they can only control load devices with a single function. With continuous improvement, this kind of switchgear has been difficult to meet the requirements of modern multi-storey, multi-room or multi-site buildings or multiple load device selections and multiple operating modes of a single load device. Functions such as forward and reverse operation of a single motor, and motor power backup selection are difficult to achieve through a single switch control, and it is difficult to meet the switching needs of diversified markets whether it is a multi-storey building or an industrial factory.

[0002] At present, when the existing switches are used to control load devices such as lamps, motors, heaters or industrial driving devices, single-switch control devices are generally used, and at the same time, they can only control load devices with a single function. With continuous improvement, this kind of switchgear has been difficult to meet the requirements of modern multi-storey, multi-room or multi-site buildings or multiple load device selections and multiple operating modes of a single load device.

Functions such as forward and reverse operation of a single motor, and motor power backup selection are difficult to achieve through a single switch control, and it is difficult to meet the switching needs of diversified markets, whether it is for multi-storey buildings or industrial factories.
