Abstract
The utility model discloses a kind of key switch, comprise pedestal, pedestal is provided with metal leg, is provided with spring in pedestal, and spring overcoat has push shaft, and push shaft is provided with contact chip, and the metal leg on pedestal is 4, and is separately positioned on 4 angles, is symmetric.The beneficial effects of the utility model: adopt 4 pin symmetric designs, use when installing and do not need travel direction identification, increase work efficiency, simultaneously in conjunction with actual needs, will be energized simplified principle, and reduce because of error frequency when circuit gear is changed, practicality is stronger.Pedestal increases notching construction newly, and can fundamentally disappear " leading directly to " hidden danger completely that exist between sunken terminal.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of key switch.
Background technology
As shown in Figure 1-Figure 3, key switch traditional in Fig. 2 and Fig. 3 needs to carry out the conversion of energising gear, and necessary travel direction identification, exists the potential safety hazard that circuit is reverse.In Fig. 3, normality: 1 and 2 conductings, 4 and 5 conductings, meanwhile, in Fig. 1, shell fragment (contact chip 4) is Split type structure, there is wherein indivedual pin positions distortion and affects whole product and to be energized bad potential safety hazard.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of novel key switch.
To achieve these goals, technical solution adopted in the utility model is:
Key switch, comprises pedestal, and pedestal is provided with metal leg, is provided with spring in pedestal, and spring overcoat has push shaft, and push shaft is provided with contact chip, and the metal leg on pedestal is 4, and is separately positioned on 4 angles, is symmetric.
Be provided with fluting in the middle of the side plate on described pedestal top, side plate is split into two halves.
Described contact chip is Contiuum type overall structure.
The beneficial effects of the utility model: adopt 4 pin symmetric designs, use when installing and do not need travel direction identification, increase work efficiency, simultaneously in conjunction with actual needs, will be energized simplified principle, and reduce because of error frequency when circuit gear is changed, practicality is stronger.Pedestal increases notching construction newly, and can fundamentally disappear " leading directly to " hidden danger completely that exist between sunken terminal.To be energized simplified principle, and electrical piece adopts " disjunctor " design simultaneously, increase energising area, and effectively improve energising performance, client practicality is in use higher, and product quality is more guaranteed; Simultaneously in conjunction with the demand of different client, can real two kinds of different modes step mode conversion.Shell fragment adopts " disjunctor ", cambered design, is out of shape little, and energising area increases.

Embodiment
As shown in Fig. 4-Fig. 6-2, key switch of the present utility model, comprises pedestal 2, and pedestal 2 is provided with metal leg 1, be provided with spring 3 in pedestal 2, and spring 3 overcoat has push shaft 5, push shaft 5 is provided with contact chip 4, metal leg 1 on pedestal 2 is 4, and is separately positioned on 4 angles, is symmetric.Be provided with fluting in the middle of the side plate on described pedestal 2 top, side plate is split into two halves.Described contact chip 4 (electrical piece) is Contiuum type overall structure.Adopt 4 pin symmetric designs, use when installing and do not need travel direction identification, increase work efficiency, simultaneously in conjunction with actual needs, will be energized simplified principle, and reduce because of error frequency when circuit gear is changed, practicality is stronger.Pedestal increases notching construction newly, and can fundamentally disappear " leading directly to " hidden danger completely that exist between sunken terminal.To be energized simplified principle, and electrical piece adopts " disjunctor " design simultaneously, increase energising area, and effectively improve energising performance, client practicality is in use higher, and product quality is more guaranteed; Simultaneously in conjunction with the demand of different client, can real two kinds of different modes step mode conversion.Shell fragment adopts " disjunctor ", cambered design, is out of shape little, and energising area increases.
As in Figure 6-1, normality: entirely disconnect; Press: 1 and 2 conductings, 3 and 4 conductings.
Shown in Fig. 6-2, normality: 1 and 2 conductings, 3 and 4 conductings, press: entirely disconnect.
