Abstract
The utility model relates to a changeover switch, which belongs to the technical field of electronic switch, comprising a casing, a diode and a button type switch mechanism. A button is connected with a casing by a shaft; the lower end of the button is provided with two raised heads; the lower part of the casing is provided with a guide rod. The utility model has the advantages of brightness selection, energy saving and prolongation of the service life of a bulb.
Description
The utility model relates to a kind of change over switch, belongs to the electronic switching technology field.
At present, the wall light switch function singleness that people generally use, brightness can't be selected, and power consumption is big, and bulb service life is short.
The purpose of this utility model is to provide a kind of change over switch, and this switch has selective light brightness, saves the function of the energy.
The purpose of this utility model is achieved in that
The housing internal upper part is provided with presses key, this press key by the axle be connected with housing, its head two ends can press respectively and be spacing by stop catch, press the key lower end and are provided with two plush coppers.The bottom is provided with guide rod in the housing, be provided with groove with the corresponding position of above-mentioned two plush coppers on the guide rod, groove and two plush coppers are complementary, the bottom of groove is provided with stage clip, one end of guide rod is connected with a binding post of housing bottom by axle, and the other end of guide rod is that moving contact is located between two fixed contacts, and one of them fixed contact connects another binding post of housing bottom, diode is located in the housing, and its two ends are connected with two fixed contacts respectively.
The utility model has the advantages that and install and use more conveniently, can exchange, except that possessing common switching function, also can on a lamp, obtain two kinds of brightness when being used for incandescent lamp control with existing switch on wall; When TV reception, can select the half-wave current state, this moment, the light and the television frame width of cloth were synchronous, weakened some lights again, so can improve the contraction frequency of pupil, reduced asthenopia; This switch also can economize on electricity, and prolongs the useful life of bulb, when being used for other resistance electric appliances, can play the effect of adjusting calorific value.
Fig. 1 is the utility model structural representation.
Fig. 2,3 is two kinds of different operating status architectures of the utility model schematic diagram.
Describe the utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1: housing 2 internal upper parts are provided with presses key 1, this press key by the axle be connected with housing, its head two ends can press respectively and be spacing by stop catch 3, press key 1 lower end and are provided with two plush coppers; The bottom is provided with guide rod 8 in the housing, on the guide rod 8 with press the corresponding position of two plush coppers, key lower end and be provided with groove, groove and two plush coppers are complementary, the bottom of groove is provided with stage clip 9, a binding post 10 of an end of guide rod 8 and housing bottom
2Connect, the other end of guide rod 8 is a moving contact 4, is located between two fixed contacts 5,7, and one of them fixed contact 7 connects another binding post 10 of housing bottom
1, diode 6 is located in the housing, and its two ends are connected with two fixed contacts 5,7 respectively.
The course of work of the present utility model is such: as shown in Figure 1, 2, 3, because pressing two plush coppers and the guide rod upper groove of key lower end is complementary, utilize friction location, mechanical dead point, make the moving contact 4 on the guide rod can be in three kinds of diverse locations, corresponding switch has three kinds of different conditions, Fig. 1 is an off state, electrical appliance does not have electric current, Fig. 2 is the diode connected state, be that moving contact 4 is communicated with fixed contact 5, electric current is communicated with another fixed contact 7 through diode 6, and Fig. 3 is that moving contact 4 directly is communicated with the fixed contact 7 that is connected end line.
