Abstract: A keyboard switch includes a base (1), a resistance-type pressure sensor (5) installed on the base (1), a spring (3) arranged in the base (1) and capable of being pressed on the resistance-type pressure sensor (5), a button (4) which presses the spring (3) and is in sliding fit with the base (1), and an upper cover (2) which presses the button (4) and is adaptive to the base (1). The resistance-type pressure sensor (5) includes two terminals (53) and an elastic sensitive element (51), the elastic sensitive element (51) being internally provided with a resistance strain gauge (52), and two leads (54) extending outwards from the resistance strain gauge (52); one ends of the two terminals (53) are respectively connected to the two leads (54), and the other ends of the two terminals (53) are separately connected to a PCB (6).

Abstract: A keyboard switch, including a base; a static contact; a moving contact; an upper cover; a button configured to control the contact of the static contact and the moving contact; and a reset spring configured to control the reset of the button.

Abstract: A keyboard switch, including a base; a static contact; a moving contact; an upper cover; a button; a reset spring; an X-shaped rack structure; and a holding part. The X-shaped rack structure includes a first connecting rack and a second connecting rack. The first connecting rack includes a first balancing lever and two first connecting parts sleeving on the first balancing lever, the second connecting rack includes a second balancing lever and two second connecting parts sleeving on the second balancing lever; opposite surfaces of the two first connecting parts each are provided with one boss, facing surfaces of the two second connecting parts each are provided with one round hole, and the boss is inserted in the round hole so that two ends of the two first connecting racks and two ends of the two second connecting racks are connected to form two X-shaped structures.

Abstract: A photoelectric switch, including: a main body, an upper cover, an infrared tube, an elastic shading mechanism, a bridge piece, a slidable switch member, a key, a sound mode trigger block, a silent mode trigger block, and an accommodating space. The slidable switch member is transversely slidable between the main body and the upper cover. The handle of the slidable switch member protrudes out of the main body. Both the sound mode trigger block and the silent mode trigger block are up-down movably disposed on the slidable switch member and move along with the slidable switch member. When the slidable switch member is slid to one side, the sound mode trigger block is disposed right beneath the key; and when the slidable switch member is slid to the other side, the silent mode trigger block is disposed right beneath the key.

Abstract: A photoelectric switch, including: a base, an infrared tube, a keycap, a balance frame, a resetting mechanism, and a light-blocking member. The light-blocking member is configured to change the propagation direction of light emitted from the infrared tube to allow or block the light propagation in the infrared tube. The infrared tube is disposed on the base. The infrared tube includes a light-emitting end and a light-receiving end. The infrared tube, the balance frame, and the resetting mechanism are disposed beneath and covered by the keycap. In operation, upon being pressed by an external force, the balance frame leads the keycap to move downwards smoothly; the light-blocking member moves upwards or downwards along with the motion of the keycap and the balance frame or the resetting mechanism. The resetting mechanism is configured to reset the keycap or the balance frame.

Abstract: An ultra-thin keyboard switch includes a base, a static contact plate, a support plate, a movable contact plate, a lower frame, an upper frame, and a keyboard cap. The static contact plate and the support plate are separated from each other and disposed on the base. The upper frame and the lower frame are intersected and pivotally connected with each other to form an X-shaped configuration to bring the movable contact plate to move. The thickness of the product can be reduced to be thin. No matter where the user's finger is at any position of the keyboard, the upper frame and the lower frame are linked to bring the movable contact plate to move. The present invention can be pressed stably, so that the connection of the static contact plate and the movable contact plate is more sensitive and the product can be used more conveniently.
