Description

keyboard

technical field

The utility model relates to a keyboard, in particular to a keyboard with improved operation sensitivity.

Background technique

Generally speaking, in a traditional remote control, the button structure is usually composed of a keycap, a conductive rubber, a switch (eg, golden finger) and a printed circuit board from top to bottom. The switch is arranged on the printed circuit board. The conductive rubber is attached to the keycap and is corresponding to the switch. In terms of operation, a user can press the key cap with a finger, so that the conductive rubber connected to the key cap touches the switch, so that the switch is turned on, and a corresponding signal is output.

However, the above-mentioned conventional button structure has many disadvantages. First of all, the user must press the center point of the keycap to touch the switch. In other words, when the user's pressing position is at the corner of the keycap, the conductive rubber will often not be able to press down on the switch, which will cause the button to press down. The problem of structural failure. Secondly, due to design and manufacturing considerations, the button structure cannot have waterproof and dustproof effects. Furthermore, the inside of the conductive rubber usually contains silicone oil. Therefore, after a long period of operation, the silicone oil in the conductive rubber often flows out due to the damage of the conductive rubber, thus damaging the entire key structure. In addition, due to the high price of the conductive rubber, the production cost of the entire key structure cannot be reduced.
