Abstract: A seat switch assembly can maintain a reliable switching operation due to enhanced durability. A pressing plate has guides which are fastened to guide holes of a base. A seat switch housing is fastened to an assembly hole of the base. An actuation rod is received inside a through-hole of the seat switch housing, and moves in the top-bottom direction in response to a pressure from the pressing plate. A V-shaped contact pin is fixed to a fixing guide of the actuation rod. One portion of a terminal pin is buried inside the seat switch housing, and the other portion of the terminal pin is exposed to the outside. A return spring is received in the lower portion of the actuation rod. A cover closes the lower portion of the through-hole. The inner surfaces of the through-hole and the terminal pin are coplanar without a stepped portion.

Abstract: It is an object of the present invention to provide a non-contact rotary movement sensor capable of, by making magnetic fields from a plurality of permanent magnets not mutually affected, independently implementing an output signal and a switching signal using the same. It is another object of the present invention to provide a non-contact rotary movement sensor provided with an independent switch which outputs an output signal by using a permanent magnet and a Hall device and outputs a switching signal using a contact switch.

Abstract: The present invention relates to a less current consuming noncontact type 2-channel rotary positioning sensor which can accurately measure the magnitude of the magnetism caused by the rotation of a rotating body by eliminating the imbalance of the magnetism that can be generated due to the eccentricity of the rotating body, by sensing with two hall element the magnitude of magnetism detected by two sensing bars located in opposite places.
