A load control device for regulating an electrical load includes: a support component including a connection portion; a knob frame including a gripping portion and an elastic portion, the gripping portion at least partially surrounding the support component and configured to drive the knob frame to rotate in response to a rotational force acting thereon, the elastic portion configured to move toward the connecting portion in response to the knob frame moving in a first direction, thereby undergoing elastic deformation; a display assembly disposed on a side surface of the knob frame facing away from the support component; a circuit board component disposed adjacent the display assembly; a switch component disposed on the circuit board component, for controlling the load in response to triggering and releasing the triggering; a switch trigger component for applying the triggering and releasing the triggering to the switch trigger component; and an adjustment component for adjusting the load in response to the rotation of the knob frame. The load control device allows for a more flexible arrangements of the switch trigger component, and makes the structure more reliable. A system including the load control device is also disclosed.

An actuator mechanism may include a first wing including a first pair of actuator pins and a first pair of housing pins, a second wing including a second pair of actuator pins and a second pair of housing pins, and a torsion element. The torsion element mechanically links the first wing with the second wing. A keycap may be pivotably coupled to the first pair of actuator pins and to the second pair of actuator pins, and a housing member may be pivotably coupled to the first pair of housing pins and to the second pair of housing pins. In response to an actuator force applied onto the keycap, the first wing and the second wing act in cooperation with the torsion element to enable parallel movement of the first wing and the second wing to actuate an electrical contact.

The present application provides a wall intelligent switch, a wireless intelligent switch and a switch mounting frame, wherein the wall intelligent switch comprises a housing, a detection member, a wireless communication module, a reset portion and at least one key; the reset acting force cooperates with a first rebound force of the detection member so that when the key is at the first pressing position, the reaction force is F1; when the key is pressed from the first pressing position to the second pressing position, the reaction force of the key jumps from F1 to F2, where F2<F1<400 g; and the difference between the displacement of the key at the first pressing position and the displacement at the second pressing position is 2 mm. This enables the keys to give clear feedback to the user while improving the smooth degree of pressing.

The present application discloses a magnetic induction micro switch with self-calibration. The micro switch includes a base provided on a printed circuit board (PCB), a housing cooperating with the base to form an installation cavity, a spring sheet installed in the installation cavity of the base via a conductive support, a limiting frame connected to a movable end of the spring sheet, and an operating member cooperating with the spring sheet and partially extending out of the housing. The spring sheet is connected to the PCB through the support and a first terminal extending downward from the base, a magnetic block is installed on the movable end of the spring sheet, and the magnetic block faces a Hall sensor located on the PCB. A movable contact is provided near a front end of the spring sheet, and a stationary contact opposite to the movable contact is provided on the base.
