An enhanced push-button includes a keycap disposed on an elastic member and having a top surface and an opposing bottom surface, and a reinforcing member mounted on the bottom surface of the keycap and having an outer surface facing the elastic member and an abutting portion located on the outer surface. The abutting portion has a contact surface recessed on the outer surface. The elastic member extends into the abutting portion such that the contact surface is abutted against the elastic member for allowing the keycap to be pressed with the reinforcing member against the elastic member to trigger a circuit switch. The invention can have better overall structural rigidity and operating feel and can maintain the pressing quality of the push-button and is suitable for low profile keyboards.

A push switch according to the present disclosure includes: a case including a recess; a fixed contact member including a fixed contact disposed in the recess; a movable contact member including a movable contact disposed in the recess; a protective sheet disposed in a first direction from the recess and covering the recess; and a rib disposed on the protective sheet. The protective sheet includes: a pressing portion; a fixed portion fixed to the case; and an intermediate portion located between the pressing portion and the fixed portion as viewed in the first direction. As the pressing portion of the protective sheet is pressed along the first direction, the movable contact member deforms by force received from the protective sheet. The movable contact touches the fixed contact as a result of the deformation of the movable contact member.

A keyswitch support connection structure incudes a bottom plate portion and a joining portion firmly joined with a joining hole of a bottom plate portion to form a support connection portion. In an embodiment, a cantilever plate extends upward from the joining hole. The joining portion encapsulates a holding structure of the cantilever plate. In another embodiment, a protruding bridge portion connected across two sides of the joining hole. The joining portion encapsulates the protruding bridge portion. In another embodiment, the joining portion has a wing portion protruding from a bottom surface of the bottom plate portion and extending parallel to the bottom surface. A keyswitch structure includes a base with the keyswitch support connection structure, a keycap, and two keyswitch supports. The two keyswitch supports are connected to and between the keycap and the base; therein, one of the keyswitch supports is rotatably connected to the support connection portion.

A keyboard device includes plural key structures. Each key structure includes a supporting plate, a keycap, a connecting member and a hook element. The keycap is located over the supporting plate, and movable upwardly or downwardly relative to the supporting plate. The connecting member is connected between the supporting plate and the keycap. The hook element is installed on the supporting plate. The connecting member is connected with the supporting plate through the hook element. The supporting plate is made of a first material with a first specific gravity. The hook element is made of a second material with a second specific gravity. The second specific gravity is higher than the first specific gravity.

A switch includes: a first electrode sheet including a first electrode; a second electrode sheet including a second electrode that faces the first electrode sheet; and an adhesive that includes a first opening through which the first electrode faces the second electrode sheet and that attaches the first electrode sheet to the second electrode sheet. The first electrode sheet includes: a first substrate on which the first electrode is disposed; a first spacer between the first substrate and the second electrode sheet that includes a second opening at a position corresponding to the first electrode; and a first base between the first substrate and the first spacer that overlaps at least a portion of an edge of the first opening of the adhesive. The first spacer is attached to the second electrode sheet by the adhesive.

A device with a keypad that includes a bezel assembled with a flexible substrate is provided. The bezel comprises: a first aperture and a second aperture separated by a retention plate. The flexible substrate comprises two or more arms joined at joining ends, and separated at distal ends, distal from the joining ends; at least one arm, of the two or more arms, comprises: a first button portion and a second button portion configured to respectively mate with the first aperture and the second aperture from a rear-side of the bezel, the first button portion and the second button portion separated by a non-button portion. The flexible substrate may be assembled with the bezel to form the keypad by inserting a distal end of the one or more arms through the first aperture from the rear-side of the bezel.

A keyswitch support connection structure incudes a bottom plate portion, a cantilever plate, and a joining portion. The cantilever plate extends upward from a joining hole of the bottom plate portion and has a holding structure. The joining portion and the joining hole are firmly engaged with each other. The joining portion encapsulates the holding structure. The joining portion and the bottom plate portion jointly form or the joining portion alone forms a support connection portion. A keyswitch structure includes a base, a keycap above the base, and first and second keyswitch supports connected to and between the keycap and the base. The base includes the above keyswitch support connection structure. The first keyswitch support is rotatably connected to the support connection portion.
