CN2311846Y - Differential place free-control switch of electric appliance - Google Patents

Abstract

The utility model provides a different place free-control electric appliance switch of an electric appliance control switch. The circuit of an electric appliance is provided with two control switches, and a binding post is additionally arranged inside an ordinary button control switch; the new arranged binding post is communicated with the other binding posts by lines, so that a terminal of a movable contact piece controlled by a button is always connected with one of the binding posts; no matter which states the button is arranged, the other switch can arbitrarily control the opening or the closing of the electric appliance so as to obtain the purpose of free control. With simple structure, low cost, and convenient operation, the utility model provides convenience for the life and production of people.

Description

The free control apparatus switch in strange land

The utility model relates to a kind of appliance switch, and the free control apparatus switch in particularly a kind of strange land is suitable for the use at the same electrical appliance of different local controls.

The electric control switch that is used for people's life at present or produces, mostly be near electrical appliance, to connect a control switch, so just can only under electrical appliance, control electrical appliance in this place in the switch place, but we often need be at two local control electrical appliances in life, if in the line the series connection of two switches or parallel connection, still exist the inconvenience of use, two switches if connect, under the situation that one of them switch disconnects, another switch has just lost control action just as ornaments, if two switches in parallel, under the situation of one of them switch in closure, another switch has lost control action too, though use delay switch can control unlatching, the time of closing can not close according to people's actual needs, not that the waste power supply is exactly not satisfy service time, always unsatisfactory, can not freely control same electrical appliance in different places simultaneously.

The purpose of this utility model provides a kind of free control apparatus switch in strange land that can optionally control same electrical appliance at different place at any time.

The purpose of this utility model is achieved in that

Two control switchs are set on the circuit of electrical appliance, in common button control switches, increase a binding post, be communicated with circuit between the newly-increased binding post, the termination of the active contacting plate of button is connected with one of them binding post all the time, like this, no matter which kind of state button is in, the another one switch can control the unlatching of electrical appliance arbitrarily or cut out, needs by people use electrical appliance, if use pulling switch, can increase a plurality of contact chips, like this, arbitrary control switch in strange land is arbitrarily controlled the use of same electrical appliance at any time.

The utility model is simple in structure, and is with low cost, easy to use, can be widely used in life or the production, in stair, passageway, corridor, parlor, bedroom or workshop, provides great convenience for people live or produce.

Following is accompanying drawing of the present utility model.

Fig. 1 is a structure diagram of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is described in further detail:

With reference to Fig. 1, in the shell 1 of button control switches, binding post 5 and binding post 4 are prior arts, increase a binding post 2, and active contacting plate 3 is prior arts.

With reference to Fig. 2, two control switchs are set on the circuit of electrical appliance 10, in a switch, increase binding post 2, in another switch, increase binding post 7, the binding post 2 and 7 that two switches are newly-increased is connected, newly-increased circuit 11, binding post 5 and 6 is communicated with, binding post 4 is connected with electrical appliance 10 respectively with binding post 9, energized is by shift knob control active contacting plate 3 or 8, if one of them switch active contacting plate 3 is communicated with binding post 4 and binding post 5, whole circuit was connected when at this moment another switch was connected binding post 6 and binding post 9 with push-button control active contacting plate 8, and electrical appliance is opened; If active contacting plate 8 is connected binding post 7 and binding post 9, entire circuit disconnects, and electrical appliance is closed.If what connect earlier is binding post 2 and binding post 4, circuit is connected when another switch connection binding post 7 and binding post 9 so, and electrical appliance is opened; Circuit disconnects when connecting binding post 6 and binding post 9, and electrical appliance is closed.Above-mentioned two switch operation principles are identical, that is to say, no matter what state a button in two control switchs is in, and the button of another switch can both freely control the unlatching of electrical appliance or cut out.

Claims (1)

1, the free control apparatus switch in a kind of strange land, comprise power supply, electrical appliance, control switch, it is characterized in that: in control switch, increase a binding post, the termination of the active contacting plate of button control is connected with one of them binding post all the time, be communicated with circuit between two newly-increased binding posts, if pulling switch then increases corresponding contact chip in switch.
