Abstract
The utility model provides a single point multi-control switch, which includes a pull switch and a plurality of parallel control switches of a clutch, the pull switch is connected in series with the electrical circuit. The utility model is characterized in that a DC motor and a transformer are added up; wherein the parallel control switches of the clutch are connected with a primary coil of the transformer in series, which form a circuit with the mains electricity; a secondary coil of the transformer is connected with the DC motor, a rotor of the DC motor is connected with the pull switch. The switch can freely control the same electrical appliance to open and close at a plurality of locations, which makes more convenient to control the electrical appliances. The utility model has a simple and novel structure, which can be widely used in various occasions of the multipoint control for the electrical appliances.
Description
Technical field
The utility model provides a kind of single-point more-control switch, belongs to contact control switch technical field.
Background technology
The many occasions that need carry out multiple spot control to same electrical equipment are arranged in the actual life, as the control of stair light at night, upstairs the time, need to turn on light at bottom of the building, just need close lamp behind the upward intact stair, so just need stair light is carried out the multiple spot control of open and close, similar same electrical equipment multiple spot control is quite a few.At this problem, the existing at present technical scheme that solves, as Chinese patent communique disclosed utility model patent on April 15th, 1998: the multiple spot single control switch, the patent No.: 96230457, form by switch enclosure and connection line, it is characterized in that: switch enclosure comprises the switch enclosure body, the switch enclosure right side plate, left side plate and cover plate, a left side, be separately installed with one group of 3 spring contact strip on the right side plate with upper contact, every group of spring contact strip all controlled by the switch removable touch panel, removable touch panel is by the button control on the cover plate, the connected mode of switching circuit is, switch terminals upper and lower contact from left and right sides two-end-point place, connecting line is intersected at middle switch contact up and down with being divided into two to be connected, middle contact switch line, also be to connect across in twos, on a left side, each switch place, control point between the right switch end points, cross-over connection has resistance and light-emitting diode.Though this switch has solved the problem of same electrical equipment being carried out multiple spot control, complex circuit.
Summary of the invention
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, single-point more-control switch simple in structure, simple to operation.
The a plurality of Parallel Control switches that comprise pulling switch and clutch, pulling switch is serially connected in the electrical appliance loop, it is characterized in that: set up DC motor and transformer, wherein a plurality of Parallel Control switches of clutch are with after the primary coil of transformer is connected in series, constitute the loop with civil power, the secondary coil of transformer connects DC motor, and the rotor of DC motor connects pulling switch.
Its operation principle is: by the control switch of next clutch, the 220V civil power is powered to DC motor after the transformer transformation, DC motor is rotated, and then pulling pulling switch closure, connects the electrical appliance loop, electrical appliance is started working, soon unclamp this control switch, the transformer loop disconnects, and stops to power to DC motor, DC motor stops operating, and pulling switch is kept closure state; When need stop electrical work, arbitrarily press the control switch of next clutch again, to the DC motor power supply, rotate by DC motor after the transformer transformation for the 220V civil power, and then the pulling pulling switch disconnects, unclamp this control switch immediately, the transformer loop disconnects, and stops to the DC motor power supply, and DC motor stops operating, pulling switch is kept off-state, and then realizes the multiple spot control to same electrical equipment.
The utility model is compared with prior art: circuit is simple, and novel structure is realized easily, can be widely used in various occasions of electrical equipment being carried out multiple spot control.

Embodiment
Pulling switch K is serially connected in the electric light Q loop, a plurality of Parallel Control switch A of clutch
1～nBe in normally open at ordinary times, after the primary coil of transformer B is connected in series, with civil power L
1, L
2Constitute the loop, the secondary coil of transformer B meets DC motor DJ, and the rotor of DC motor DJ connects the backguy 1 of pulling switch K.Press the control switch A of clutch
1, the 220V civil power is given DC motor DJ power supply after transformer B transformation, and DC motor DJ rotates, and then through backguy 1 pulling pulling switch K closure, connects electric light Q loop, and electric light Q is bright, soon unclamps this control switch A
1, primary B wire loop disconnects, and stops the power supply to DC motor DJ, and DC motor DJ stops operating, and pulling switch K keeps closure state; When turning off the light, arbitrarily press a control switch A of clutch
n, transformer B get electric and transformation after give DC motor DJ power supply, DC motor DJ rotates, and then disconnects through backguy 1 pulling pulling switch K, electric light Q does not work, and soon unclamps this control switch A
n, transformer B primary coil loops disconnects, and stops the power supply to DC motor DJ, and DC motor DJ stops operating, and pulling switch K keeps off-state, realizes the multiple spot control of electric light Q.
Electric light Q among the embodiment also can be other electrical appliance.
