Abstract
The invention discloses a mechanical-type membrane keyboard switch, aiming at providing a mechanical-type membrane keyboard switch which is infatigable and has long service life. The mechanical-type membrane keyboard switch comprises a connecting push rod (1), a key seat (3), a return spring (2) and a film laminating component (4). The key seat (3) is provided with a sliding chute (6) in the middle and the connecting push rod (1) is arranged in the sliding chute (6) and can slide in the sliding chute (6) up and down. One end of the return spring (2) is connected with the connecting push rod (1) while the other end is connected with the key seat (3), and the film laminating component (4) is arranged at the bottom of the key seat (3). The invention relates to a mechanical-type membrane keyboard switch.
Description
Technical field
The present invention relates to a kind of mechanical thin-film keyboard switch.
Background technology
