Abstract
The utility model discloses a non-contact switch. The non-contact switch comprises a switch body, a power portion and a control circuit portion, wherein the power portion provides power for the control circuit portion, a proximity sensor is used for sensing whether an object is in a sense range, each time the proximity sensor senses proximity of the object, the proximity sensor sends a triggering signal to a trigger one time, a relay takes the triggering signal of the trigger as a control signal to directly realize on-off control of a 220V circuit. The non-contact switch has advantages of stability and university of a traditional switch as well as convenience, hygiene, electric shock proofness, water proofness, and the like.
Description
Technical field
The utility model relates to a kind of control switch, and particularly a kind of utilization is near the non-contact switch of induction technology.
Background technology
In the life, we usually can touch various switches.Open each time or close, with regard to the meaning set about with switch between to once contact.Such contact meeting brings potential harm to us, such as germ and electric shock.Exist acoustic control in the market, switch product such as light-operated has improved above-mentioned situation to a certain extent, but that their exist on stability, universality is a lot of not enough, this also is the reason that conventional switch still occupies main flow market.
The utility model content
The purpose of the utility model is exactly in order to solve the deficiency of traditional contact-making switch and acoustic control, light-operated switch, for this reason, to propose a kind of passing through and realize contactless switch near induction technology.When unlatching or off switch, only need hand is got final product near a switch.It has the stability and the universality of conventional switch, also has characteristics such as waterproof simultaneously.
To achieve these goals, the utility model adopts following technical scheme.
The non-contact switch of the utility model comprises Switch main body, power unit and control circuit part.Power unit is that control circuit is partly supplied power, and control circuit partly comprises the relay that links to each other successively, and d type flip flop and proximity transducer, proximity transducer are positioned at the Switch main body front side.
Proximity transducer be used to respond to whether have object induction range in; Proximity transducer whenever detect object near; Just give triggering signal of trigger, said relay as control signal, is directly controlled the break-make of 220V power circuit with the triggering signal of d type flip flop.
Said power unit can adopt traditional transformation rectification circuit, and the 220V alternating current is transformed into the 5V direct current, is used for partly supplying power to control circuit.
The beneficial effect of the non-contact switch of the utility model is, both had the stability and the universality of conventional switch, has characteristics such as convenient and healthy, protection against electric shock, waterproof again simultaneously.
Description of drawings
Fig. 1 is the square principle figure of the utility model.
Wherein, 1, power unit; 2, relay; 3, d type flip flop; 4, proximity transducer.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
The non-contact switch of the utility model comprises Switch main body, power unit 1 and control circuit part.Power unit 1 is partly supplied power for control circuit, and control circuit partly comprises the relay 2 that links to each other successively, d type flip flop 3 and proximity transducer 4, and proximity transducer 4 is positioned at the Switch main body front side.
Switch main body can adopt and the design of conventional switch similar in appearance, comprises switch enclosure base two parts, so that identification,
Its outside line connects identical with conventional switch, and directly being connected into existing line can use.
Proximity transducer 4 is positioned at the switch front side, and whether be used to respond to has object in the induction range of 5-10cm.When object is arranged, output 5V logic high; During no object, output 0V logic low.
When proximity transducer 4 whenever detects object successively, then give 3 triggering signals of d type flip flop; At this moment, the output of d type flip flop 3 will be accomplished 0V saltus step to 5V or 5V to 0V.
Connect through above-mentioned circuit, realize from the approaching break-make control of sensing power circuit of staff.
Though the above-mentioned accompanying drawing that combines is described the embodiment of the utility model; But be not restriction to the utility model protection range; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection range of the utility model.
Claims (2)
1. a non-contact switch comprises Switch main body, power unit and control circuit part, it is characterized in that; Power unit is that control circuit is partly supplied power; Control circuit partly comprises the relay that links to each other successively, and d type flip flop and proximity transducer, proximity transducer are positioned at the Switch main body front side; Proximity transducer be used to respond to whether have object induction range in; Proximity transducer whenever detect object near; Just give triggering signal of trigger, said relay as control signal, is directly controlled the break-make of 220V power circuit with the triggering signal of d type flip flop.
2. non-contact switch as claimed in claim 1 is characterized in that, said power unit adopts traditional transformation rectification circuit, the 220V alternating current is transformed into the 5V direct current, for control circuit is partly supplied power.
