A surface mount device switch includes a pedestal, a flexible conducting element and a metal dome. The flexible conducting element is connected with the pedestal. There is a spacing distance between the flexible conducting element and a circuit board. The metal dome is located under a pedestal conducting part of the pedestal and the flexible conducting element. When the flexible conducting element is pushed by the metal dome, the flexible conducting element is deformable in the direction toward the circuit board. Since the collision between the metal dome and the flexible conducting element is alleviated, the noise is reduced. Consequently, the comfort of operating the touchpad module is enhanced. The present invention further provides a touchpad module and a computing device with the surface mount device switch.

A stroke adjustment cover for clip-type micro switch, the stroke adjustment cover comprises a cover body connected to a clip-type micro switch, a stroke adjustment member disposed in the cover body, and an elastic member used to provide the stroke adjustment member with a reciprocating stroke perpendicular to the direction of an actuation stroke of the clip-type micro switch. Through an adjustment section of the stroke adjustment member includes at least one brake portion used for braking the clip-type micro switch to generate the actuation stroke in the reciprocating stroke provided by the elastic member. The present invention not requires modification of the actuation stroke and structure of the clip-type micro switch, while an actuation time of a switching command signal of the clip-type micro switch is extended by the stroke adjustment cover provided with the different reciprocating strokes and being easy to install.

The present disclosure provides a household appliance and a control assembly which includes a control panel, a display screen and a power switch. The display screen is arranged on the control panel and can move relative to the control panel. The power switch is connected to the control panel and/or the display screen for controlling the power-on and power-off of the household appliance. When the display screen is pressed, the display screen moves relative to the control panel and controls the power-on or power-off of the power switch. By pressing the display screen to control the power-on and power-off of the power switch, a complete power-off can be achieved to eliminate the drawbacks of weak power and incomplete power-off of the touch-sensitive power switch, and the arrangement of a power switch key is omitted, therefore the operation and the overall appearance of the household appliance is simplified.

An actuator device which includes a fixed support structure, an actuation member movable, a biasing member tending to maintain the actuation member in a rest position, a shape-memory wire connected to the structure and to the actuation member, and an electric circuit for supplying an electric current to the shape-memory wire. The circuit includes a pair of terminals. One end of the shape-memory wire is connected to a first terminal. The circuit includes further an electric switch, including a first conducting member electrically connected with the second terminal, and a second conducting member carried by the actuation member and electrically connected with the other end of the shape-memory wire. The switch is closed when the actuation member is in the rest position, and remains closed until when the actuation member reaches a working position, and opens when the actuation member passes beyond the working position.
