Abstract
The utility model relates to a concealed box-typed switch, comprising a box body (1), a box cover (2), a press key (3), contact pieces (6), (7), (8), movable pieces (9), (10), a diode (11) a screw and a screw nut. The contact piece (7) is arranged between the contact piece (6) and the contact piece (8); the voltage reducing diode (11) is connected between the contact piece (7) and the contact piece (8); two piece shapes are matched with each other mutually; the movable pieces (9), (10) of the contact pieces (6), (7), (8) can be communicated as required; the longitudinal center of the movable piece (9) is provided with a small round recess used for positioning the press key; when the switch is opened, the diode experiences an instantaneous middle process of voltage reduction; the instantaneous impact pressure of a power supply when the power supply is switched on; the utility model can be used to transform two kinds of light with different intensity when used to control the illumination of electrical lights.
Description
The utility model relates to the cassette switch of control apparatus power supply.
Cassette switch now only has the function that switches on and off power supply, and when this class switch was used for the control apparatus power supply, power surges voltage was bigger during owing to unlatching, and electrical equipment is caused certain infringement, has shortened the useful life of electrical equipment.
The cassette switch of excessive surge voltage when the utility model can provide a kind of capable of reducing power source open.
The utility model is made up of polymer box body, polymer lid, button, three metal contacts, two metal moving plates, diode and screw-nut.A left side contact and right contact are fixed on the two ends, the interior end of box body with terminal screw, cambic in contact be fixed between left and right two contacts with plain screw.Between middle contact and left contact, connecting buck diode.Mate mutually with last moving plate shape, following moving plate is supported in the groove of right contact, and vertically central authorities have the recessed last moving plate of Yi Xiaoyuan to be superimposed upon down on the moving plate and by the push rod of button to withstand.
When the left head of button was pressed, moving plate was gone up in the compressing of button push rod and following moving plate leaves middle contact and left contact, and switch is in off-state; When button was pressed " putting down ", the button push rod peaked at the little garden recess of moving plate, and substantially parallel moving plate down of last moving plate and compressing moving plate down contact right contact and middle contact simultaneously, and switch is in on-state, and the step-down of electric current process diode; When the right head of button was pressed, the compressing of button push rod was gone up moving plate and is contacted left, center, right three contacts simultaneously with following moving plate, and switch is in pass-through state, and diode is inoperative, and the voltage that switch passes through is consistent with supply voltage.
This step-down switching is compared with existing switch, has the following advantages:
1, can protect electrical equipment.When electrical equipment was enabled, because this switch will experience the pilot process of an instantaneous diode step-down in opening process, the temporary impact voltage during unlatching capable of reducing power source was so can protect electrical equipment to exempt from the infringement of surge voltage, the useful life of prolongation electrical equipment.
2, can conversion electric light light intensity.When this switch was used to control lamp lighting, step-down was communicated with the position and normal pressure is communicated with two grades of positions owing to have, so the light of convertible two kinds of different brightness.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is upper and lower moving plate figure of the present utility model
Fig. 3 is left, center, right contact figure of the present utility model
In structural representation shown in Figure 1, box body of the present utility model (1), lid (2) and button (3) adopt box body, lid and the button of common cassette switch.Three contact shapes as shown in Figure 3, they adopt 1 to 2 millimeters thick copper sheet to make, its left contact (6) and right contact (8) are fixed on the two ends, the interior end of box body (1) with terminal screw, and contact (7) was fixed between left contact (8) and the right contact (6) with plain screw during it was cambic.Diode (11) adopts common withstand voltage diode, and its bipod is connected on the hold-down screw of middle contact (7) and left contact (8).Last moving plate (9) and following moving plate (10) as shown in Figure 2, their adopt 1 to 2 millimeters thick copper sheet to make, following moving plate (10) is supported in the groove of right contact (6), last moving plate (9) is superimposed upon down on the moving plate (10).After the box inner part installs, refill lid (2), its button push rod (5) should withstand on the moving plate (9).
Claims (2)
1, the cassette switch of a kind of energy step-down comprises box body (1), lid (2), button (3), contact (6), (7), (8), moving plate (9), (10), diode (11), it is characterized in that being added with between left contact (6) and the right contact (9) the middle contact (7) of a transition nature, between middle contact (7) and left contact (8), connect a diode (11) that is used for step-down, and have two plate shapes to mate, can be communicated with as required moving plate (9) and (10) of contact (6), (7), (8) mutually.
2,, it is characterized in that vertical central authorities of moving plate (9) have a little garden that is used for the button location recessed according to right 1 described cassette switch.
