Abstract

The utility model discloses a touch switch button with better operation flexibility. The touch switch button comprises an annular body. The end surface of one end of the annular body is an operating surface, and the end surface of the other end of the annular body is a push-down surface. The push-down surface faces to a touch switch contact area. The internal wall of the annular body is provided with a button contact, the end surface of which is opposite to the touch switch contact area. The internal wall of the annular body is provided with the button contact, thereby ensuring that the contact position of a button and the touch switch contact area is changed from the edge part to the middle part, the operation flexibility is higher; in addition, the button contact can increase the strength of the button, so as to ensure that the annular body is manufactured as being thinner under the condition of satisfying the strength requirement; the touch switch button saves material, so as to reduce the weight; the touch switch button can be operated by the contact of the button contact and the touch switch contact area; for the prior button, the diameter of the annular body can be increased, so as to increase the comfort for operating the button. The touch switch button is particularly fit for the application in batch production.

Description

The touch-switch button

Technical field

The utility model relates to a kind of button, especially a kind of button that cooperates touch-switch to use.

Background technology

At present, in the household electric appliances, most products all will use button, realize control to complete machine by button and contacting of touch-switch.Described button generally adopts engineering plastics to make, comprise annular solid, the end face of annular solid one end is an operating surface, the end face of the annular solid other end is for depressing face, the face of depressing is relative with the touch-switch contact zone, and when depressing operating surface, the face of depressing contacts with the touch-switch contact zone, turn-on control circuit is realized the control operation to product.Because the mid portion of touch-switch contact zone is highly sensitive in marginal portion sensitivity, therefore, when using the button of aforementioned structure, feel " blunt " may appear, that is the not enough situation of Operational Figure Of Merit.

The utility model content

In order to overcome the sensitive inadequately deficiency of existing touch-switch button operation, technical problem to be solved in the utility model provides the better touch-switch button of a kind of Operational Figure Of Merit.

The technical scheme that its technical problem that solves the utility model adopts is: the touch-switch button, comprise annular solid, the end face of annular solid one end is an operating surface, the end face of the annular solid other end is for depressing face, the face of depressing is towards the touch-switch contact zone, the inwall of annular solid is provided with the button contact, and the end face of button contact is relative with the touch-switch contact zone.

The beneficial effects of the utility model are: by the button contact is set on the inwall of annular solid, make the contact site of button and touch-switch contact zone become mid portion from the marginal portion, make Operational Figure Of Merit higher, and, the button contact can strengthen the intensity of button, thereby satisfying under the condition of requirement of strength and can partly do annular solid thinner, saving material, to alleviate button weight; Can only utilize the button contact to operate, for existing button, the diameter of annular solid can be increased, to increase the comfort of button operation with contacting of touch-switch contact zone.

Be labeled as 1-touch-switch, 2-button, 11-touch-switch contact zone, 21-operating surface, 22-annular solid, 23-button contact, the free end of 24-button contact among the figure.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, touch-switch button of the present utility model, comprise annular solid 22, the end face of annular solid 22 1 ends is an operating surface 21, the end face of annular solid 22 other ends is for depressing face 25, depress face 25 towards touch-switch contact zone 11, the inwall of annular solid 22 is provided with button contact 23, and the end face of button contact 23 is relative with touch-switch contact zone 11.Because the sensitivity of touch-switch contact zone 11 is descended gradually by middle mind-set edge, after the architecture advances to button 2, the button contact 23 that is provided with on the inwall of annular solid 22 has improved operational sensitivity facing to the mid portion of touch-switch contact zone 11.Described button contact 23 is arranged on the inwall of annular solid 22, and promptly button contact 23 both can be arranged on the inner bottom surface of annular solid 22, also can be arranged on the madial wall of annular solid 22.

More laborsaving when making operator's button, the end face of described button contact 23 and depress face 25 on a face.The shape of the end face of annular solid 22 and button contact 23 thereof should be corresponding with the external surface shape of touch-switch contact zone 11, can be the plane, also can be cambered surface etc.When button 2 was depressed, the end face of button contact 23 is very fast to be contacted with touch-switch contact zone 11.

Consider that Mold Making and injection moulding are easy to process, as Fig. 2 and shown in Figure 5, described button contact 23 is along the radially setting of annular solid 22.

In addition, in order further to improve the sensitivity of button operation, as Fig. 2 and shown in Figure 4, described button contact 23 1 ends are free end 24, free end 24 should extend to the center of annular solid 22, that is with 11 centers, touch-switch contact zone over against the position, so the sensitivity at 11 centers, touch-switch contact zone is the highest.

Feel is more comfortable when making button operation, as shown in Figure 1, can make the diameter of the internal diameter of annular solid 22 greater than touch-switch contact zone 11, only utilizes the end face of button contact 23 to contact with touch-switch 1.

Because button contact 23 has increased the intensity of button 2, so the wall thickness of annular solid 22 can do thinlyyer than existing, with economical with materials, and weight reduction.

When touch-switch button of the present utility model being applied to occasions such as domestic electrical equipment remote controller, generally a plurality of button one can be injection-moulded on the button substrate, with ease of assembly.
