Abstract
A thin switch includes a pressing cup (1), a base (2) and a top cover (3). A conductive component (4), a spring (5), a fixed terminal (6) and an elastic wire (7) are disposed in a space defined by buckling the base and the top cover. The elastic wire is arranged below the conductive component, one end of the elastic wire is fixed on the base and the other end is disposed under a boss of the pressing cup. When the pressing cup is pressed down, the conductive component is driven to contact the fixed terminal to turn on the switch, and the elastic wire is driven to descend at the same time. When the pressing cup is pressed down to a preset position, the elastic wire separates from the pressing cup, and bounces back upwards to strike the dome to make a sound.
Claims16
A thin switch, comprising:
- a base (2) comprising a guide column protruding upwardly;
- a spring (5) sleeved on the guide column;
- a fixed terminal (6) secured to the base, comprising at least one conductive contact configured on a top surface thereof and a first IO terminal electrically connected with the at least one conductive contact and protruding out of the base;
- a pressing cup (1) covered on the guide column and supported by the spring, comprising a boss protruding outwardly from a side wall thereof;
- an annular conductive component (4) comprising a second IO terminal protruding out of the base and an annular part sleeved on the pressing cup;
- an elastic wire (7) with a first end fixed to the base and a second end extending to a position under the boss of the pressing cup;
- and
- a top cover (3) connected with the base to forming a receiving space and defining an opening to allow an upper part of the pressing cup to protruding out thereof;
- wherein when the pressing cup is pressed downwardly, the spring is compressed, at least a part of the annular conductive component is driven to descend and contact with the at least one conductive contact of the fixed terminal to turn on the switch, and the second end of the elastic wire is pressed downwards accordingly by the boss at the same time;
- wherein when the pressing cup moves down to a preset position, the second end of the elastic wire slides beyond an edge of the boss and bounces back upwards to strike the annular conductive component to make a sound.
A keyboard switch, comprising:
- a base plate (A);
- a thin switch (D) fixed on the base plate;
- a key cap (B);
- a scissor supporter (C) fixed on the base plate and supporting the key cap above the thin switch;
- wherein the thin switch comprises:
- a base (2) comprising a guide column protruding upwardly;
- a spring (5) sleeved on the guide column;
- a fixed terminal (6) secured to the base, comprising at least one conductive contact configured on a top surface thereof and a first IO terminal electrically connected with the at least one conductive contact and protruding out of the base;
- a pressing cup (1) covered on the guide column and supported by the spring, comprising a boss protruding outwardly from a side wall thereof;
- an annular conductive component (4) comprising a second IO terminal protruding out of the base and an annular part sleeved on the pressing cup;
- an elastic wire (7) with a first end fixed to the base and a second end extending to a position under the boss of the pressing cup;
- and
- a top cover (3) connected with the base to forming a receiving space and defining an opening to allow an upper part of the pressing cup to protruding out thereof;
- wherein when the key cap is pressed downwardly, the pressing cup is pressed downwardly by the key cap, the spring is compressed, at least a part of the annular conductive component is driven to descend and contact with the at least one conductive contact of the fixed terminal to turn on the switch, and the second end of the elastic wire is pressed downwards accordingly by the boss at the same time;
- wherein when the pressing cup moves down to a preset position, the second end of the elastic wire slides beyond an edge of the boss and bounces back upwards to strike the annular conductive component to make a sound.
