Abstract
The utility model provides a multi-way contact switch, comprising trigger circuits, each of the trigger circuits is composed of an NOT-AND gate, a charging circuit, a thin film switch, and a triode. The NOT-AND gate is formed by two NOT gates connected in series, the two input ends of the NOT-AND gate are connected through a resistor, the output end of the NOT gate is connected with the base electrode of the triode through the resistor, the collector electrode of the triode is connected with the gate electrode of a controlled silicon, the controlled silicon is connected in series with an electric appliance, a charging circuit is connected with the output end of the NOT-AND gate, the thin film switch is connected between the input end of one NOT gate and a charging capacitor, and a plurality of trigger circuits which are mutually connected in parallel are provided. The utility model can cause the switches of a plurality of electric appliances to be arranged together, having the advantage of convenient use.
Description
The utility model relates to a kind of electronic switch.
At one family, have many kinds of electrical appliances, because soft-touch control in the market all is a single channel, the switch of controlling these electrical equipment generally all disperses to be installed in everywhere, makes troubles to use.Such as, during toilet, need feel about in the dark and walk to the corridor on the midnight desire, look for the toilet lamp switch again; For another example, TV is seen in bed, and just before going to bed, need leave the bed switches off the TV.
The purpose of this utility model is: a kind of variable connector is provided, and it can concentrate in together installation with the switch of multiple electrical equipment, brings convenience to the user.
The purpose of this utility model is achieved in that by NAND gate, charging circuit RC, thin film switch and triode forms circuits for triggering, NAND gate is to be composed in series by two not gate A1 and A2, two inputs of NAND gate connect by resistance, the output of not gate A2 is connected on the base stage of triode by resistance, the collector electrode of triode is connected with the silicon controlled gate pole, controllable silicon is connected with electrical appliance, charging circuit RC is connected on the output of NAND gate, thin film switch is connected between the input and charging capacitor C of A1, above-mentioned circuits for triggering have some, and are parallel with one another.Operation principle is: after thin film switch is connected, 1 pin (input of A1) by NAND gate charges to charging capacitor C, C is short circuit in the moment of charging, so 1 pin is a low level, 2,3 pin are high level, 4 pin are low level, return 1 pin by resistance, produce self-locking, simultaneously the triode conducting, trigger also conducting of controllable silicon, electrical equipment is opened; When pressing thin film switch again, charging capacitor C discharges to 1 pin, and 1 pin is a high level, and 2,3 pin are low level, and 4 pin are high level, and triode ends, and controllable silicon also ends, and electrical appliance is closed.Because it is parallel with one another and can integrate that above-mentioned circuits for triggering are several, the film soft-touch control that therefore can control respective numbers electrical equipment can be fitted together.
The utility model compared with prior art, it can be installed together the switch of a plurality of electrical appliances, such as, the switch of television set, toilet lamp and bedroom lamp is positioned on the bedside cupboard, very easy to use; Compare with mechanical switch, it is low to have a cost, advantage such as volume is little, easy for installation and attractive in appearance.
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is an electrical schematic diagram of the present utility model.
By NAND gate, charging circuit R5C3, thin film switch K1 and triode T1 form circuits for triggering, NAND gate is to be composed in series by two not gate A1 and A2, two inputs of NAND gate connect by resistance R 4, the output of not gate A2 is connected on the base stage of triode T1 by resistance R 3, the collector electrode of triode T1 is connected with the gate pole of controllable silicon SCR 1 by light-emitting diode D1, controllable silicon is connected with bulb F1, charging circuit R5C3 is connected on the output of NAND gate, thin film switch is connected between the input and charging capacitor C3 of A1, above-mentioned circuits for triggering have three, parallel with one another, control three electrical equipment F1-F3.Operation principle is: after thin film switch is connected, 1 pin (input of A1) by NAND gate charges to charging capacitor C3, C3 is short circuit in the moment of charging, so 1 pin is a low level, 2,3 pin are high level, 4 pin are low level, return 1 pin by resistance R 4, produce self-locking, simultaneously the triode conducting, trigger also conducting of controllable silicon, bulb is bright; When pressing thin film switch again, charging capacitor C3 discharges to 1 pin, and 1 pin is a high level, and 2,3 pin are low level, and 4 pin are high level, and triode ends, and controllable silicon also ends, and bulb goes out.Since above-mentioned circuits for triggering be three parallel with one another and can integrate, the film soft-touch control that therefore can control respective numbers electrical equipment can be fitted together.
Claims (2)
1, a kind of multichannel soft-touch control, it is characterized in that: form circuits for triggering by NAND gate, charging circuit RC, thin film switch and triode, NAND gate is to be composed in series by two not gate A1 and A2, two inputs of NAND gate connect by resistance, the output of not gate A2 is connected on the base stage of triode by resistance, the collector electrode of triode is connected with the silicon controlled gate pole, controllable silicon is connected with electrical appliance, charging circuit RC is connected on the output of NAND gate, thin film switch is connected between the input and charging capacitor C of A1, above-mentioned circuits for triggering have some, and are parallel with one another.
