Abstract

The utility model relates to a universal square switch, which is used for controlling indoor electric appliances. A miniature motor is arranged in a switch box, the rotating shaft of the miniature motor is fixed with an elastic movable contact, the elastic movable contact is contacted with a circle of fixed contacts one by one, and the electric appliances can be turned on and off at multiple positions.

Description

Universal square switch

The utility model is a kind of control switch that indoor electric appliance is installed that relates to.

Known appliance switch is of a great variety.People have designed the different switch of function for various purposes easily.But because demand is many-sided, thereby the kind of switch does not satisfy actual needs forever.In daily life, people just need be at the same electrical equipment of different Position Control.As entering a building in the dark, need the switch opens gateway lamp that a palpable position is provided with at the place of entering, be prompted by economy motives, switch shutoff lamp downstairs should be arranged after going upstairs.Of this sort demand is a lot, but existing switch seldom has this function, and therefore, it is with practical value developing such product.

The purpose of this utility model promptly is to provide a kind of switch with above-mentioned functions, and described switch has can finish the function that multiposition opens and closes same electrical equipment.

For achieving the above object, scheme of the present utility model is: be provided with a micromotor in switch enclosure, its rotation axis is fixed an elasticity movable contact, one circle fixed contact is set in elasticity movable contact plane in one's power, described elasticity movable contact and fixed contact are serially connected in respectively in the outer circuit, simultaneously electrical appliance and one group of point driving switch are serially connected.

Every non-conterminous two of above-mentioned fixed contact couples together with conductor, be connected in series with external circuit and movable contact again, like this when the elasticity movable contact contacts with the contact that couples together with conductor, circuit debugging, and circuit disconnects when the elasticity movable contact contacts with other contact.

Adopt said apparatus, in the desired position point driving switch is set, its number depends on the needs, and is unrestricted, just reach the purpose that diverse location is controlled same electrical equipment, so this programme realized the purpose of this utility model.

Below by embodiment scheme of the present utility model is done detailed explanation.

Fig. 1 is the front view of Universal square switch;

Fig. 2 is the vertical view of Universal square switch;

Fig. 3 is that Universal square switch A-A is to cutaway view;

Fig. 4 is the front view of another embodiment of Universal square switch;

Fig. 5 is the vertical view of another embodiment of Universal square switch;

Fig. 6 is the electrical schematic diagram of Universal square switch;

Figure 1 shows that an embodiment of Universal square switch, comprise an electrical micro-machine (1), the model of micromachine is YM-01, rotating speed is 20 commentaries on classics/per minutes, micromachine (1) has rotating shaft (2), the axial end of rotating shaft (2) has an aperture, described elasticity movable contact is a spring (3), one end of spring (3) passes the aperture of motor shaft, make the elasticity movable contact can be fixed on the axle, in 360 ° of included areal extents of spring contact (3) rotation, be provided with a circle fixed contact (4), number need be provided with at least two or more.Described fixed contact (4) is a cylindricality, and an end of post is fixed on the base plate (5) with nut.Micromachine (1) also is fastened on the base plate (5) with screw.The back side in base plate (5) couples together per two non-conterminous fixed contacts (4) with lead (10), as shown in Figure 3, and connects with external circuit, and its principle is seen shown in Figure 6.Also be connected to one group of point driving switch (6) in the sequential circuit of switch, electrical appliance (7) also is serially connected in the same circuit.Point driving switch (6) can be contained in diverse location, depends on the needs.

Embodiment 2 is the multidigit open-close on-off of another kind of contact form, still be provided with a micromachine (1), described elasticity movable contact (8) is a microscler sheet, one end is the flat plush copper of garden shape, the other end is porose, movable contact (8) can be imported in the axle (2), axle (2) end is provided with the silk mouth, compress a spiral elastic ring (11) with nut, make elasticity movable contact (8) can press to fixed contact (9) tightly, fixed contact (9) is still by last example distribution one circle, the contact site of fixed contact (9) is a garden flat, wholely is shaped as T shape, is fixed on the base plate (5) with screw, still resemble overleaf Fig. 3 and connect two non-conterminous fixed contacts with between lead time, and by in the schematic diagram tie-in line shown in Figure 6.

The Universal square switch of two kinds of embodiment of the present utility model, its operating principle are the same basically.Micromotor is connected during the point driving switch installed on pressing diverse location, and the elasticity movable contact is slowly rotated, and contacts with fixed contact one by one, makes circuit connect a disconnection, when the state of needs occurs, unclamps point driving switch and gets final product.

The Universal square switch that the utility model is designed, simple in structure, reliable, cheap, be a kind of effective utility model.
