This electronic component, electronic component terminal structure and electronic device do not use solder, and as a result, make it possible to prevent an environmental impact, reduce assembly cost and reduce the burden on an electrical connecting section. An electronic component equipped with an electronic component main body and a conductive terminal, wherein the terminal is a coil spring which is expandably fitted into a guide groove provided to the electronic component main body, and contacts a printed circuit board while in a compressed state. For example, the guide groove extends in a prescribed direction and connects the interior of the electronic component main body and the exterior thereof to one another, and the coil spring is supported so as not to fall to the exterior side of the electronic component main body from the guide groove.

This electronic component and electronic apparatus enable the rotational torque to be sufficiently increased, enhance the waterproofing performance, and enable easy soldering of a terminal onto a circuit board. The electronic component comprises: an electronic component body that is disposed inside a case and that is installed on the surface of a circuit board facing the inside of the case; an input shaft that passes through a cylindrical section that follows the surface from the electronic component body and is provided to the case, the input axis extending to the outside of the case; and a fitting member that fits into the gap between the cylindrical section and the input shaft. For example, the fitting member is provided with a ring-shaped section that includes: an inner edge in contact with the input shaft; and an outer edge in contact with the cylindrical section.

A split-type electromagnetic induction joystick potentiometer includes a handle circuit board provided with at least one joystick mechanism installation position and at least one joystick mechanism installed on the at least one joystick mechanism installation position. Each joystick mechanism installation position is welded with a magnetic induction chip. Each joystick mechanism includes a base, a sliding disc, a spring, a joystick, a rocker arm, an upper cover and a housing. The magnetic induction chip is directly welded onto the handle circuit board, without the need for separate design and manufacturing of a magnetic induction circuit board to weld the magnetic induction chip. Each joystick mechanism of the disclosure itself is not installed with the magnetic induction circuit board, thereby simplifying the manufacturing and assembly process of the split-type electromagnetic induction joystick potentiometer, and reducing the manufacturing costs. The permanent magnet can interact magnetically with the magnetic induction chip.

Disclosed in the present invention is a short-range optical potentiometer module, comprising a potential base body provided with a key slot, and a potential key which is mounted inside the key slot and can be displaced up and down, wherein a reset member for resetting the potential key is also arranged inside the key slot, an optical pair transistor composed of a photosensitive element and a light-emitting element is arranged inside the potential key, the optical pair transistor can be displaced up and down along with the potential key, a key base is internally provided with a fixed grating corresponding to the optical pair transistor, the reset member is sleeved on the grating, and the grating is configured such that the flux of light received by the photosensitive element from the light-emitting element changes along with the up-and-down displacement of the potential key, thereby causing an electrical signal generated by the photosensitive element to change along with the displacement of the potential key. The module of the solution uses non-contact photoelectric elements, thereby greatly increasing the service life; when the change in flux of light at the same distance is adjusted, the overall height of the module is close to or the same as the height of a potential base body; and the module has a skillful overall structure layout, can be conveniently assembled and replaced, and has strong practicality.
