A key structure includes a base plate, a triggering element, a keycap and a scissors-type connecting element. The base plate includes an open-type hook and a bulge. The scissors-type connecting element includes a first frame and a second frame. The first frame includes a first base post and an elastic contact part. Due to the structure of the open-type hook, the first frame can be easily assembled with the base plate. Moreover, it is not necessary to retain the gap between the first base posit and the open-type hook. While the first frame is swung, the elastic contact part is pushed by the corresponding bulge. Consequently, the first base post is not detached from the base plate.

Described herein are thin keyboard and thin keyboard overlay, as well as novel key assembly for uses on keyboards and keyswitches. The key assembly includes a top plate, a movable keycap, a support plate and flexible rods embedded in the sup port plate acting as springs. The underside of the movable keycap has at least one or several tapered protrusions which are located above the flexible rods. A vertical downward force on the movable keycap will enable the protrusion to flex the rods horizontally, thus creating a spring like mechanism that will return the movable keycap to its original position once the vertical force is removed.

An electronic module is provided including a circuit board a first conductive track, second conductive tracks, third conductive tracks mounted on a first surface of the circuit board; at least one first heat sink mounted on the first conductive track; second heat sinks mounted respectively on the second conductive tracks; motor terminals formed through the third conductive tracks; and power switches mounted on the second surface of the circuit board configured as an inverter circuit to supply power from a power supply to an electric motor. High-side power switches are located opposite the at least one first heat sink and in thermal communication therewith, and low-side power switches are located opposite the second heat sinks and in respective thermal communication therewith.

The present invention discloses a dual-actuator switch, comprising: a base, a first electrical connection member, a second electrical connection member, a first isolation sleeve cylinder, a second isolation sleeve cylinder, a first actuator, a second actuator, and a cover. By pressing one of the two actuators to drive one of the two isolation sleeve cylinders to rotate, the isolation sleeve cylinder is driven to prop one of the two electrical connection members by a protrusion member thereof, such that one of two switching operations is carried out. It is worth noting that, the electrical connection members are isolated from the actuators by the isolation sleeve cylinders during the whole electrical switching procedures. As a result, ambient moisture is absolutely blocked from getting into the base for infiltrating the electrical connection members during the up and/or down motion of the actuators.

Provided is a switch that can be downsized. A switch is provided with a plunger, two upper torsion springs that bias the plunger in a returning direction, housing-side contacts, and plunger-side contacts. One of the upper torsion springs is arranged on one side of a plane that includes an axis passing through a central portion of the plunger, and that is perpendicular to perpendicular lines M connecting the plunger-side contacts and the axis, and the other one of the upper torsion springs is arranged on the other side of the plane.

A balance mechanism (180) and a keyboard switch (100) including the balance mechanism (180) are provided. The balance mechanism (180) comprises a first frame (181) and a second frame (182) rotatable relative to each other, which are both of hollow structures with matched shapes and sizes. When the first frame (181) and the second frame (182) are in a superimposed state, a dynamic contact (130) and a static contact (120) are electrically connected. A relative rotation between the first frame (181) and the second frame (182) drives the moving contact (130) to move, achieving separation and contact between the dynamic contact (130) and the static contact (120), thereby turning on and off the switch. The keyboard switch (100) is thin, thus achieving miniaturization of the switch; the switch prevents a guide core (160) from tilting and being stuck in the button, which is convenient for operation.

A switch component includes a spring plate and a cover of rubber. The cover of rubber covers at least one part of an upper surface of the spring plate. The cover of rubber includes at least one pair of supporting portions that support the spring plate.

A key structure includes a base plate, a triggering element, a keycap and a scissors-type connecting element. The base plate includes an open-type hook and a bulge. The scissors-type connecting element includes a first frame and a second frame. The first frame includes a first base post and an elastic contact part. Due to the structure of the open-type hook, the first frame can be easily assembled with the base plate. Moreover, it is not necessary to retain the gap between the first base posit and the open-type hook. While the first frame is swung, the elastic contact part is pushed by the corresponding bulge. Consequently, the first base post is not detached from the base plate.

A switching assembly can include a lever arm that is magnetically attached to at least a portion of a base plate. A contact may be positioned in a spaced apart and above one end of the lever arm. Alternatively, the contact may be included in the base plate. Another switching assembly can include a movable element adapted to electrically connect with a contact in the switch assembly and a guide a guide having a geometry that directs the element along a first travel path to the contact and a second travel path away from the contact. A geometry of the guide is based on a first displacement curve that is associated with the first travel path and on a second displacement curve that is associated with the second travel path.

A strip light switch includes an insulative housing with terminal grooves and positioning grooves defined in an accommodation chamber therein, a terminal set including at least one first terminal, at least one second terminal and multiple third terminals mounted in the terminal grooves and multiple mating connection terminals detachably mounted in the positioning grooves in a replaceable manner for conduction with the third terminals, a conductive shrapnel mounted in the accommodation chamber, and a press device including a cylindrical press block supported on the conductive shrapnel pressable by a user to force the conductive shrapnel in conducting the first and second terminals, conducting plates mounted in the cylindrical press block and disposed in contact with the conducting plates of the mating connection terminal and a light-emitting component mounted in the cylindrical press block for electrical contact with the conducting plates.
