Abstract
The utility model relates to an electrical element, in particular to a double-contact switch which comprises a support, an upper cover, a button, a bouncer, a bounce spring, a thrust spring and a contact plate, wherein, the upper cover is fixedly connected on the support which is fixedly provided with two electrodes; inner ends of the electrodes are arranged inside the support while outer ends thereof are positioned outside the support; the upper cover is internally provided with the bounce spring, the bouncer and the button in sequence; the contact plate and the thrust spring are arranged in the support; the contact plate is clamped between the thrust spring and the bounce spring and the surface of the contact plate is attached to the two electrodes. Since only two electrodes are arranged, the electrical element of the utility model has the advantages of simple structure, good durability and wide range of application.
Description
Technical field
The utility model is a kind of electric elements, particularly a kind of double contact switch.
Background technology
Switch of the prior art mostly is four contacts, because the complex structure of four contact switchs, so several times have more than is needed, internal mechanism will break down, thereby causes scrapping of whole switch.In addition, under most occasions, double contact switch uses more some morely, if replace double contact switch with four contact switchs, also is a kind of waste.
Summary of the invention
The purpose of this utility model is in order to overcome the limited defective of the complicated scope of application of four contact switch structures, to invent a kind of double contact switch that utilizes bouncing mechanism to realize out and close.
The purpose of this utility model realizes as follows: described double contact switch, comprise support, loam cake, button, spring part, spring spring, thrust spring and contact plate, loam cake is fixed on the support, be installed with two electrodes on the support, the inner of electrode is positioned at support, the outer end of electrode is positioned at outside the support, be provided with spring spring, spring part and button in the loam cake successively, be provided with contact plate and thrust spring in the support, contact plate is located between thrust spring and the spring spring, and the plate face of contact plate pastes mutually with two electrodes.
Cover on described and be provided with fixture.
Good effect of the present utility model is as follows: owing to only be provided with two electrodes, so simple in structure, durable in use, applied widely.
Description of drawings
Fig. 1 is the utility model structure chart
Among the figure: 1 support, 2 loam cakes, 3 buttons
4 spring parts, 5 spring springs, 6 thrust springs
7 contact plates, 8 electrodes, 9 fixtures
Embodiment
As shown in Figure 1, described double contact switch, comprise support 1, loam cake 2, button 3, spring part 4, spring spring 5, thrust spring 6 and contact plate 7, loam cake 2 is fixed on the support 1, be installed with two electrodes 8 on the support 1, the inner of electrode 8 is positioned at support 1, the outer end of electrode 8 is positioned at outside the support 1, be provided with spring spring 5, spring part 4 and button 3 in the loam cake 2 successively, be provided with contact plate 7 and thrust spring 6 in the support 1, contact plate 7 is located between thrust spring 6 and the spring spring 5, and the plate face of contact plate 7 pastes mutually with two electrodes 8.
Described loam cake 2 is provided with fixture 9.Fixture 9 is to be used for this switch is fixed on circuit board.
The utility model is by button 3, spring part 4, and spring spring 5 constitutes bouncing mechanism, presses button earlier, under the bouncing mechanism effect, contact plate 7 contacts with electrode, and circuit turn-on clicks button again, and bouncing mechanism lifts, under the effect of thrust spring 6, contact plate 7 breaks away from electrode, and circuit disconnects.
