Abstract

The invention discloses a combined type right-cone dual spring and a pluggable independent direct capacitance keyboard switch, and aims to provide a combined type right-cone dual spring which is simple in structure, convenient to mount and favorable for improving the production efficiency, and also provide a pluggable independent direct capacitance keyboard switch which is simple in structure, convenient to mount and easy to replace. The combined type right-cone dual spring (1) comprises a key cap push rod resetting spring (11) and a conical spring (12), wherein after sleeving the top of the conical spring (12), the bottom of the key cap push rod resetting spring (11) is connected with the bottom of the conical spring (12). The pluggable independent direct capacitance keyboard switch comprises the combined type right-cone dual spring (1), a key seat, a key cap push rod and a limiting card which are integrated. The combined type right-cone dual spring and the pluggable independent direct capacitance keyboard switch are applied to the technical field of direct capacitance keyboard switches.

Description

technical field [0001] The invention relates to a spring and a switch, in particular to a combined straight-cone double spring and a pluggable independent static capacitance keyboard switch. Background technique [0002] At present, office and gaming keyboards are divided into two categories and a small category based on keyboard switches: the two categories are membrane keyboards and mechanical keyboards, and the small category is silicone bowl electrostatic capacitance keyboards. The silver paste contacts of the first category of membrane keyboard switches are easy to oxidize, and the silicone bowl is easy to fatigue; the metal contacts of the second category of mechanical keyboard switches also have oxidation problems, which have high requirements for the use environment, dust and liquid are mechanical switches The fatal factor of shortened service life; the third sub-category is the silicone bowl electrostatic capacitive keyboard switch, whose service life is also limite...
