Key switch capable of switching silence and voiced state

Abstract

The invention discloses a key switch capable of switching between a mute state and a voiced state. The key switch comprises an insulating base, a shell, a switching button and a return spring, the plurality of terminals are provided with first to fourth closed ends at the top of the insulating base in an exposed manner, the first closed end and the second closed end are located in the first switch area, and the third closed end and the fourth closed end are located in the second switch area; the first switch area is provided with a micro switching elastic sheet, and a micro switch button is arranged in the shell; the second switch area is provided with a metal dome. The switching button is rotatably arranged in the shell; when the switching button rotates to the first working position, the switching button presses the microswitch button to press the microswitch switching elastic piece, and when the switching button rotates to the second working position, the switching button presses the middle upper arch part of the metal dome elastic piece. Therefore, a better pressing operation hand feeling and ideal switching sensitivity are obtained in the voiced mode, and in the silent mode, the light touch switch can better meet the silent requirement and better meet the customer requirement.

Description

technical field [0001] The invention relates to the technology in the field of key switches, in particular to a key switch that can switch between mute and sound. Background technique [0002] Taking the mouse button switch as an example, in order to facilitate the user, the audio and silent button operation experience can be selected according to their own preferences and environmental requirements. [0003] Later, a key switch that can switch between sound and sound appeared. This switchable key switch uses two tact switches to realize the switch between mute and sound, although it passes through the upper arch of the dome of the tact switch. The design of the arch height of the tactile switch is different, and it can realize two operating modes: sound and silent. However, in the sound mode, the touch switch has a poor sense of pressing and switching and the operation is unreliable, which cannot meet the requirements of customers. Moreover, the two tact switches are indiv...

Problems solved by technology

[0003] Later, a key switch that can be switched freely with sound / silent appeared. This kind of switchable key switch uses two tact switches to switch between mute and sound, although it passes through the upper arch of the dome of the tact switch. The design of the arching height is different, and two operation modes of sound / silent can be realized. However, in the sound mode, the light touch switch has a poor sense of pressing and switching, and the operation is unreliable, which cannot meet the requirements of customers.

Moreover, the two tact switches are individually designed with terminals, and one active arm on the guide core is stuck on the limit spring, so that the other active arm on the guide core is facing the position of a spring. This switching operation mode, The toggle stroke is relatively large when switching, and the switching operation part is the bottom end of the guide core. The flat-shaped screwdriver mouth at the bottom end of the guide core is used as the switching operation part. The screwdriver mouth drives the guide core to rotate as a whole, thereby changing the position of the action arm, which is troublesome to operate

In addition, since the bottom end of the guide core needs to protrude from the bottom of the base of the housing, it will inevitably occupy the design space of the base of the housing, causing the position of the terminals on the base to be slightly shifted outward, resulting in the size of the entire key switch bigger

The size of the entire key switch is different from that of the mouse switch used in large quantities in the current market. The existing structure of the mouse on the client side needs to be greatly changed, which makes it difficult to promote.
