Abstract: An operator for controlling electrically adjustable furniture includes a housing and an actuation panel movably supported in the housing to form a cover body. A circuit board is provided in the housing, and a main control unit for detecting an actuation signal is provided on the circuit board. A first switch for generating a first actuation signal and a second switch for generating a second actuation signal are provided between the actuation panel and the main control unit, and a third switch for generating a third actuation signal is provided between a bottom wall of the housing and the main control unit. The main control unit issues a first command when simultaneously detecting the first actuation signal and the second actuation signal, and the main control unit issues a second command when simultaneously detecting the first actuation signal, the second actuation signal, and the third actuation signal.

Abstract: A continuously variable speed controller comprises an operating unit, an operation detector coupled to the operating unit to detect a continuous variation of an action of the operating unit, an information processor electrically connected to the operation detector to obtain a corresponding motor speed variation quantity based on a detection result from the operation detector, and a motor controller electrically connected to the information processor to receive the motor speed variation quantity and adjust a speed of the motor continuously based on the motor speed variation quantity. As such, speed control becomes more intuitive, and can achieve stepless speed change, while no need to set the speed switch to occupy the control and detection ports, simplifying structure of the product.
