Abstract

The utility model relates to a light touch switch. The switch comprises a cover plate, a button, a spring sheet, a terminal and a pedestal. A geometric center of the cover plate is provided with a through hole which is cooperated with the button. One part of the button is exposed in air. The cover plate and an inner part of the pedestal form a cavity. The light touch switch also comprises a button carrier which plays a limit role between the button and the cover plate. The button carrier and the button are in a clamping fixation state. One part of the terminal is embedded in the pedestal and the other part is exposed in the cavity. The exposed portion is located below the button. The spring sheet is arranged between the button and the exposed portion. The light touch switch possesses the following characteristics that a service life is long; contact is stable and so on.

Description

Touch-switch

Technical field

The utility model relates to a kind of touch-switch, relates in particular to a kind of touch-switch.

Background technology

At present, this class touch-switch mainly is made of cover plate, button, shell fragment, terminal and pedestal, and multiplex in the portable type electronic products such as mobile phone, MP3, digital camera, usually adopt button pressed downwards to make shell fragment and termination contact connect or close, existing shell fragment and termination contact are also unstable, make malfunctioning switch, the serious switch that more may cause damages.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of contact stabilization, touch-switch simple in structure.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

a kind of touch-switch, it comprises cover plate, button, shell fragment, terminal and pedestal, cover plate geometric center place offers the through hole that coordinates with button, a button part is exposed in air, described cover plate and base interior form cavity, wherein, this touch-switch also comprises the button carrier that plays position-limiting action between button and cover plate, button carrier and button are plug-in to be fixed, the part of described terminal is embedded in pedestal, another part is exposed in cavity, exposed part is positioned at below button, shell fragment is arranged between button and exposed part, described shell fragment has 2 arc surfaces, the summit of described arc surface contacts with the upper surface of terminal exposed part.

Wherein, described shell fragment is double-deck.

Adopt on shell fragment 2 arc surfaces be set, the summit of arc surface contact with the upper surface of terminal exposed part such design make between shell fragment and terminal contact more stable, the life-span of having improved switch.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:

see also Fig. 1, a kind of touch-switch, it comprises pedestal 1, terminal 2, the shell fragment 3 of two-layer identical shaped formation, button 4, button carrier 5 and cover plate 6, offer the through hole that coordinates with button 4 on cover plate 6, button 4 is exposed in air by a through hole part, button carrier 5 is plug-in with button 4 to be fixed, button carrier 5 with button 4 clampings after make button carrier 5 upper surface can and the cover plate inwall offset, thereby button carrier 5 plays position-limiting action between button 4 and cover plate 6, cover plate 6 and the inner cavity that forms of pedestal 1, the part of terminal 2 is embedded in pedestal 1, another part is exposed in cavity, exposed part is positioned at button 4 belows, shell fragment 3 is arranged between the exposed part of button and terminal 2, shell fragment 3 has two arc surfaces 31, the summit of arc surface contacts with the upper surface of terminal 2 exposed parts.
