Abstract

The invention discloses a potentiometer that comprises a movable block, a base body block and a potential adjusting structure; the movable block is embedded into the base body block; the potential adjusting structure is arranged on the movable block; a magnetic conductive attraction block structure is embedded into the part, far away from the potential adjusting structure, of the movable block; magnetic conductive sheets are attracted at the end parts, extending out of the movable block, of the magnetic conductive attraction block structure; the magnetic conductive sheet is embedded and fastened on the base body block, the base body block is provided with a Hall element corresponding to the potential adjusting structure, the movable block can move relative to the base body block, the position relation between the potential adjusting structure and the Hall element is changed, and therefore the Hall element is affected by changes of a surrounding magnetic field to generate correspondingHall potential changes. The position relation between the potential adjusting structure on the base body block and the linear Hall element is changed, stepless or geared Hall potential adjustment is achieved, the adjustability is good, the magnetic conductive attraction block structure can be attracted to the magnetic conductive sheet together after being abraded, the service life is long, and stability is good.

Description

technical field [0001] The invention relates to the technical field of switch elements, in particular to a potentiometer. Background technique [0002] At present, quite a few Hall potentiometers, switches, etc. use the Hall effect, generally including Hall elements, permanent magnets and springs. The permanent magnets are close to the Hall elements to make the Hall potential of the Hall elements change, making the Hall effect The circuit connected with the Hall element will produce corresponding changes, such as the Chinese patent with the patent application number "2018214016136" and the patent name "A Safety Switch", including a base, a shaft, a spring, a magnetic element and a Hall element, the spring, The magnetic element and Hall element are located in the base, at least a part of the shaft can be located outside the base, and the rest of the shaft is located in the base, one end of the spring is in contact with the shaft, and the other end of the spring is in contact ...
