Abstract

The invention relates to a pushbutton switch having a ring in which a spring-prestressed button is arranged such that it can be pushed in a predetermined actuating displacement. The button has a top side terminating flush with the top edge of the ring, and from at least one side of the ring parallel to the longitudinal axis of an actuating finger, the edge of the ring is reduced continuously in height substantially to the level of the actuating displacement.

Description

Push-button switch

The present invention relates to a kind of push-button switch.

The round button switch is familiar with by people, its diameter 15 and 25mm between and an annulus is arranged, spring precompressed button is installed in the annulus, button can be pressed into a preset distance like this, the end face of button is the plane, with the top of annulus along concordant.In this case, annulus is used for button is fixed on the installation surface and the guiding finger is reliable and operation accurately, also is used to avoid the misoperation that causes owing to unconscious contact.

Yet in the pressing operation process, finger tip partly contacts with on every side annulus.Especially the long people of nail feels inconvenient or uncomfortable, mainly is because long nail also can contact with the appropriate section of annulus usually.

This problem can solve by the operating distance that reduces button.But this needs the motor machine of certain precision on the one hand, and needs the approval of the push-button sense of hearing or vision on the other hand.

If reduced the height of annulus, button will protrude, and the result is that annulus loses it pointed and avoided the device of misoperation as guiding effect.

The purpose of this invention is to provide a kind of as the described push-button switch ofclaim 1 preorder, it can operate button easily, even the relevant personnel have long nail, and can not lose annulus as the effect that guides the device of pointing and avoid misoperation with without any need for approval.

This purpose is achieved according to the qualifying part ofclaim 1.

Other structure of the present invention can be understood from following narration and other dependent claims.

Typical embodiment with reference to the accompanying drawings makes more detailed description to the present invention.

Fig. 1 is to the different embodiment of Fig. 3 with perspective representation round button switch.

According to embodiment shown in Figure 1, the external diameter round button switch in 15 to 25mm scopes greatly comprises anannulus 1, and this annulus is mainly used in push-button switch is fixed on theinstallation surface.Annulus 1 holds a button 2, and this button has aflat end face 3 and is installed in theannulus 1, and button can be pressed into a predetermined operating distance like this.

Annulus 1 has acircular top interface 4, reduces at the height with the parallel circular top interface, relative bothsides 4 of the longitudinal axis of the people's of console switch operation finger.Thereby, its top is reduced to the height of the height after approximately moving corresponding to button 2 operations highly gradually along beginning along the interface,top 4 concordant with theflat top surface 3 of button 2 from the top, this top is along being formed by two corresponding points vertical with the longitudinal axis of operation finger, herein, interface,top 4 is concordant with theflat top surface 3 of button 2.In operating process, because the position of nail is higher slightly than the finger tip of executable operations action, the operating distance of the comparable button 2 of formed difference in height is slightly little.

Under situation embodiment illustrated in fig. 3,1 of annulus is in the corresponding reduction of a side height.

With regard to embodiment shown in Figure 2, toroidal design must with Fig. 1 in identical, but the interface,top 4 of thesurface 3 of button 2 andannulus 1 adapts, thereby described surface design must be concordant with described interface.

Even the people of action button 2 has long nail, this button also can be operated easily, and annulus can not lose it pointed and avoided the device of misoperation as guiding effect.

Claims (4)

1. push-button switch, has an annulus (1), one spring roof pressure button (2) is installed in the annulus, thereby button can be pressed into a predetermined operating distance, the top of button (2) and annulus (1) is along concordant, wherein, the height of annulus (1) is reduced to the height that is about after operation is moved gradually at least one side of the longitudinal axis that is parallel to the operation finger.

2. push-button switch as claimed in claim 1, wherein, annulus (1) reduces on two opposite sides highly equally.

3. push-button switch as claimed in claim 2, wherein, the end face (3) of button (2) is the plane.

4. push-button switch as claimed in claim 2, wherein, the end face (3) of button (2) designs corresponding to the profile at annulus (1) interface, top (4) and mutually concordant with it.
