Abstract
A keyswitch device includes a bottom plate, a keycap, and a position-returning member. The keycap includes a metal cover and a covering member. The metal cover includes a first main body. The first main body has a first surface and a second surface respectively facing toward and facing away from the bottom plate. The first surface presents a pattern. The covering member includes a second main body covering the first surface. The second main body has a light-transmitting area covering the pattern. The position-returning member is disposed between the bottom plate and the keycap and contacts the first main body.
Claims7
A keyswitch device, comprising:
- a bottom plate;
- a keycap comprising:
- a metal cover comprising a first main body and a first edge bending portion, the first main body having a first surface and a second surface respectively facing toward and facing away from the bottom plate and an engaging hole communicated to the first surface and the second surface, the first surface presenting a pattern, the first edge bending portion being connected to the first main body;
- a covering member comprising a second main body and a second edge bending portion, the second main body covering the first surface and having a light-transmitting area covering the pattern, the second edge bending portion being connected to the second main body;
- an adhesive material adhering the first edge bending portion and the second edge bending portion;
- and
- an engaging structure fixed to the first main body and protruding from the second surface, wherein the engaging structure is embedded in the engaging hole;
- a position-returning member disposed between the bottom plate and the keycap and contacting the first main body;
- and
- a connecting assembly connected between the bottom plate and the engaging structure and configured to guide the keycap to move upward and downward relative to the bottom plate.
A keyswitch device, comprising:
- a bottom plate;
- a keycap comprising:
- a metal cover comprising a first main body and a first edge bending portion, the first main body having a first surface and a second surface respectively facing toward and facing away from the bottom plate, the first surface presenting a pattern, the first edge bending portion being connected to the first main body;
- a covering member comprising a second main body and a second edge bending portion, the second main body covering the first surface and having a light-transmitting area covering the pattern, the second edge bending portion being connected to the second main body, wherein the first edge bending portion has at least one recessed hole facing the second edge bending portion;
- and
- an adhesive material adhering the first edge bending portion and the second edge bending portion, wherein a part of the adhesive material is accommodated in the at least one recessed hole;
- and
- a position-returning member disposed between the bottom plate and the keycap and contacting the first main body.
