Problems solved by technology

However, all the switch metal shrapnel currently used for the switch type, if they are stamped into a high-stroke, there will be undesirable phenomena such as non-conduction or flickering when lightly pressed.
At present, only Apple in the United States has used stamped high-stroke metal shrapnel on the function keys of its latest version of the ultra-thin laptop keyboard, but it cannot directly conduct electricity, and it needs to be in the position of the conductive contact. Add metal sheet for on-off function
[0003] In view of this, it is necessary to improve the switch metal shrapnel in the prior art to solve the problem that the switch metal shrapnel cannot use the function of the shrapnel itself to turn on and off the power

Abstract

The invention relates to a light transmittance on-off switch metal elastic piece for a key. A C-shaped light transmittance hole is formed in the center of a product, a conducting block on the inner side of the light transmittance hole is provided with a contact, the contact can be directly used for conducting, power-on is achieved by lightly pressing the contact, and power-off is instantly achieved when the contact is loosened. The structure of the switch metal elastic piece is optimized based on existing high stroke and hand feeling value and long service life, and elastic piece deformation is improved to overcome the shortcoming that on-off cannot be achieved by the aid of functions of the elastic piece.

Description

technical field [0001] The invention relates to a button part, in particular to a light-transmitting on-off switch metal shrapnel used in conjunction with the button. Background technique [0002] The metal shrapnel used in the button is generally made of ultra-thin (0.05mm~0.1mm thick) stainless steel material, which has the advantages of stable contact, strong conduction, and stable rebound. It is an important part of the button and can be Plays a good switch enable and control role. However, if all the switch metal shrapnels currently used for switches are stamped into high strokes, there will be undesirable phenomena such as non-conduction or flashing when pressed lightly. At present, only Apple in the United States has used stamped high-stroke metal shrapnel on the function keys of its latest version of the ultra-thin laptop keyboard, but it cannot directly conduct electricity, and it needs to be in the position of the conductive contact. Add metal sheet for on-off ...
