Description

A magnetically controlled double control switch circuit

technical field

The utility model relates to the technical field of circuit design, in particular to a magnetically controlled double-control switch circuit.

Background technique

In the home circuit, we often encounter such a problem: when entering the door at night, because the room is dark, the light of the room must be turned on first. At this time, the designer usually installs a switch to control the lighting at the door. However, the location of the bed in the bedroom is usually not placed at the door. In this way, the position of the rest and the position of the control light switch are not together, and the switch must be turned off at the door to turn off the light, so that the switch of the control light cannot be used conveniently; this problem also exists in some corridor lights. If the switch of the corridor light is placed at the entrance of the corridor, when a person reaches the upstairs, he must go downstairs to turn off the corridor light. On the contrary, the switch is installed at the exit of the upstairs corridor, and the one-way control of the floor lamp cannot be performed after going down the stairs. Visible, for some special environments, if the switch of electric light can only be controlled from one place, will bring bigger inconvenience to life.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a magnetically controlled double-control switch circuit that can realize switches in different positions to control one electric lamp.

The technical solution of the present invention is: a magnetically controlled dual-control switch circuit, including a power supply, a first line, a second line and a third line, the first line includes a circuit connected in series between the positive and negative poles of the power supply The switch S1 and the first electromagnetic device, the second line includes a switch S2 and the second electromagnetic device connected in series between the positive and negative poles of the power supply, the third line includes the lamp connected to the positive pole of the power supply and the electric lamp The switch iron sheet D in series, the magnetic force surfaces of the first electromagnetic device and the second electromagnetic device are arranged oppositely, and the switch iron sheet D is arranged between the first electromagnetic device and the second electromagnetic device and has an equal distance from the two electromagnetic devices, The first electromagnetic device and the second electromagnetic device have the same structure.

Further, the first electromagnetic device includes an electromagnet B1 and a contact copper sheet C1. One end of the electromagnet B1 is connected to the negative pole of the power supply, and the other end is connected to the switch S1. One end of the contact copper sheet C1 is connected to the negative pole of the power supply. The contact copper piece C1 is corresponding to and not in contact with the electromagnet B1.

Further, the magnetic force surface distance of the first electromagnetic device and the second electromagnetic device structure is smaller than the magnetic force range.

The beneficial effect of the utility model is: the parallel connection of the first electromagnetic device and the second electromagnetic device is adopted, and the switch iron sheets are disconnected or pulled in by closing different switches, so as to realize the double switch control of an electric lamp. In special occasions, only two switches need to be arranged in the two required positions, which can realize the double switch control of the electric light and bring greater convenience to life. Maintaining a gap between the contact copper and the magnet reduces the effect of magnetization. The distance between the magnetic surface of the first electromagnetic device and the second electromagnetic device structure is set to be smaller than the magnetic force range, so as to ensure that the switch iron sheet is in the attraction range of the two electromagnetic devices and ensure the stability of the switch control.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

As shown in FIG. 1 , a magnetically controlled dual-control switch circuit of the present application includes a power supply E, a first circuit, a second circuit and a third circuit. The first circuit includes a switch S1 and a first electromagnetic device connected in series between the positive and negative poles of the power supply E. The second circuit includes a switch S2 and a second electromagnetic device connected in series between the positive and negative poles of the power supply E. The third line includes an electric lamp O connected to the positive pole of the power supply E and a switch iron sheet D connected in series with the electric lamp O.
