Abstract
The utility model relates to a magnetic control switch, comprising a control circuit and magnet. The control circuit consists of a resistance, a capacitance, a diode, a triode, a tongue tube and a relay which are all connected; when the magnet is enabled to get close to the tongue tube, the tongue tube switches the relay circuit through, and then the relay operates to make the entire switch circuit through; when the magnet is enabled to go far from the tongue tube, the tongue tube disconnects the relay circuit, and then the relay is separated to disconnect the entire switch circuit. The magnetic control switch can be directly arranged in the 220V circuit or the circuit with lower voltage such as 36V or 12V, with stable performance and reliable operation. When the magnetic control switch is arranged on a cabinet door or room door, the switch of the circuit can be controlled by the switch of the door, thus energy is saved. The magnetic control switch has the advantages of no contact, small size, low cost and convenient installation and use.
Description
Technical field
The utility model relates to a kind of contactor, especially a kind of contactor that utilizes magnetic force control.
Background technology
At present, the furniture on the market some within it portion electric light is installed, for example wardrobe or desk are installed electric light in wardrobe or in the drawer, light switch is contained in outside wardrobe door or the drawer.Back warp often need use lighting in the toilet of many office spaces or family, switch generally is located at outdoors or the inside, toilet, more than the switch that uses of two class places all be the common contact-type switch usually, people need to open switch before use, connect lamp power supply, need off switch after the use, sometimes, can forget after people use and turn off the light, cause electric light often to open, the waste electric energy.
The utility model content
At the deficiency of above existing light switch, the purpose of this utility model provides a kind of magnetic switch of realizing switching lamp in the switch door.
The purpose of this utility model is achieved by the following technical solution:
Magnetic switch, comprise control circuit and magnet, control circuit comprises resistance, electric capacity, diode, triode, tongue tube and relay, magnet when the tongue tube, tongue tube engage relay circuit, the relay adhesive, whole switching circuit is connected, and magnet is during away from tongue tube, and tongue tube disconnects relay circuit, relay separates, and whole switching circuit is disconnected.
As another technical scheme of the utility model magnetic switch, magnet when the tongue tube, tongue tube engage relay circuit, the relay adhesive disconnects whole switching circuit, and magnet is during away from tongue tube, tongue tube disconnects relay circuit, and relay separates, and whole switching circuit is connected.
In the technical scheme of the utility model magnetic switch, described control circuit also comprises photo resistance.
The beneficial effect of the utility model magnetic switch is: by above structure as can be known, magnetic switch comes switching on and off of control circuit by magnet, tongue tube and relay, can be installed in the circuit of low-voltages such as 220V, 36V, 24V, 12V, stable performance, reliable operation, magnetic switch is installed in the switch that the switch that can utilize door on cupboard door or the room door comes control circuit, help energy savings, magnetic switch is contactless, volume is little, cost is low, easy to install.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the circuit diagram of the utility model magnetic switch.
Embodiment
As shown in Figure 1, magnetic switch, comprise control circuit and magnet, control circuit is formed by connecting by resistance, electric capacity, diode, triode, tongue tube and relay, resistance has R1 and R2, electric capacity has C1 and electrochemical capacitor C2, and diode has rectifier diode D1 and voltage stabilizing didoe D2, and triode is Q1.When magnet M when the tongue tube S, tongue tube S engage relay RE circuit, relay R E adhesive is connected whole switching circuit, magnet M is during away from tongue tube S, tongue tube S disconnects relay R E circuit, relay R E separates, and whole switching circuit is disconnected.This routine magnetic switch is installed on the bathroom door, can realizes connecting lamp power supply at closing time, the back of opening the door disconnects lamp power supply.
Another embodiment of the utility model magnetic switch, the A contact and the H contact circuit of Fig. 1 repeat circuit are exchanged, when magnet M when the tongue tube S, tongue tube engage relay RE circuit, relay R E adhesive disconnects whole switching circuit, magnet M is during away from tongue tube S, tongue tube S disconnects relay R E circuit, and relay R E separates, and whole switching circuit is connected.This routine magnetic switch is installed on wardrobe door or the drawer, connects lamp power supply in the time of can realizing opening wardrobe door or drawer, disconnect lamp power supply after shutting wardrobe door or drawer.
The 3rd embodiment of the utility model magnetic switch adds photo resistance respectively among the control circuit of above two embodiment, can realize the light control functionality of switch.
Claims (3)
1, magnetic switch, comprise control circuit and magnet, control circuit comprises resistance, electric capacity, diode, triode, tongue tube and relay, it is characterized in that: magnet when the tongue tube, tongue tube engage relay circuit, the relay adhesive, whole switching circuit is connected, and magnet is during away from tongue tube, and tongue tube disconnects relay circuit, relay separates, and whole switching circuit is disconnected.
