JPH0511247U - Push button switch - Google Patents

Abstract

(57) [Summary] [Purpose] The tact switch and the push button that pushes it operate smoothly. [Structure] A pressing part locked to the panel by a locking part, a projecting part and a branch part provided on the inner circumference of the pressing part, and an elastic piece integrally formed on the panel are in contact with the upper projecting part when pressed. The elastic piece bends and turns the switch on and off at the branch.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a push button structure that constitutes a push button switch provided in a panel operation unit of an electronic device.

[0002]

[Prior Art]

 3 (a) and 3 (b) are cross-sectional views of the main part of the conventional push button switch, and the operation thereof will be described. The push button 11 is provided so as to project from the front surface of the electronic device panel 12, and the switch 14 wired to the substrate 13 is turned on and off by the branch portion 11a that projects toward the back surface of the push button 11.

[0003]

[Problems to be solved by the device]

 As shown when the push button is pressed, when the pressing portion 11a is pressed, the pressing feeling becomes slanted, and the panel 12 has to be fixed via the fixing portion 11b, which is a workability problem. .

[0004]

[Means for Solving the Problems]

 The present invention is made to solve the above-mentioned drawbacks.When the pressing portion is pushed from the front, the elastic piece integrally formed with the panel and the protruding portion provided on the inner peripheral portion of the switch come into contact with each other, and the elastic piece of the elastic piece is Since the stroke is increased and the spring action is sufficiently provided, it is possible to provide a switch structure that smoothly turns the switch ON and OFF and has a good pressing feeling.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. 1 (a) and 1 (b) are side sectional views of an essential part showing an embodiment of the present invention, in which a panel 2, a push button 1 attached to the panel 2, an elastic piece 2a integrally formed with the panel, and a substrate. The elastic piece 2a of the panel 2 constituted by the switch 4 wired in 3 contacts the protruding portion 1b provided on the inner peripheral portion of the push button 1 and is integrally formed on the panel 2 by pushing the push button 1 from the front. The elastic piece 2a thus bent bends to press the switch 4 with the branch 1a protruding from the back surface of the push button 1 to turn it on and off.

By pressing the push button 1 from the front side, it is possible to configure a push button having a good operation feeling that the switch 4 is turned on and off. Further, the panel 2 is provided with a concave portion 2b for locking the push button 1, and the concave portion 2b pushes out the elastic engaging piece 1c of the push button 1 from the slit 2c to the back side of the panel 2 for engagement. The elastic piece of the panel 2 is constructed so that a sufficient stroke can be taken as shown in FIG.

[0007]

[Effect of the device]

 According to the present invention, when a push button is pressed, a push button switch having a good operation feeling can be obtained without using a spring.
