Abstract: Provided is an electromagnetic induction potentiometer adaptive for full-stroke detection, including a movable element configured to obtain an input for position change, a permanent magnet attached to the movable element, a magnetic induction sensor configured to sense positions of the permanent magnet and generate an initial potential signal, and an full-stroke adaptive output adjusting unit configured to collect the initial potential signal and adaptively adjust the initial potential signal to an actual potential signal corresponding to a full stroke of position changing of the movable element.

Abstract: A game controller key includes a base, a casing and a key switch. The casing is fastened to the base to form a cavity; the key switch is disposed in the cavity; the top of the key switch is exposed from a surface of the casing; conductive silica gel is installed at the bottom of the key switch; a through hole is provided at a position on the base that corresponds to the conductive silica gel; a spring is installed between the key switch and the base; a side wall of the key switch is provided with a first bump; a plate body is installed on the base; a gap is present between each of two sides of the plate body and the base; and the plate body is provided with a second bump matching the first bump. The spring is used for controlling the force of the key.
