Multi-directional switch device

摘要

A multi-directional switch device includes: an operation shaft to which an operation knob is mounted to perform a rotating operation and a tilting operation; and a housing, which supports the operation shaft. In the housing, a circuit board which has a second fixed contact on the lower surface, a wafer which has a first fixed contact, a rotation holder which rotates integrally with the operation shaft while allowing oscillation of the operation shaft, a rotation slider which rotates integrally with the operation shaft and slides during the tilting operation, a first movable contact, and a second movable contact are arranged. When the operation shaft is rotated and thus the rotation holder is rotated from a rotation neutral position by about 180 degrees, a first signal is output. When the operation shaft is tilted while the rotation holder is rotated by about ±45 degrees, a second or third signal is output.

1. A multi-directional switch device comprising:
an operation shaft configured to perform a rotating operation and a tilting operation and having an operation knob at one end portion; and a housing which supports the operation shaft so as to be rotatable and tiltable, wherein, in the housing, a circuit board which has a through-hole through which the operation shaft penetrates, a first fixed contact and a second fixed contact formed integrally with the circuit board, a rotation holder through which the operation shaft is inserted in a loosely-fitted state in which oscillation of the operation shaft is allowed and which rotates integrally with the operation shaft, a rotation slider through which the operation shaft is inserted to rotate integrally and which slides linearly along the circuit board by being driven by the tilted operation shaft, a first movable contact which is held in the rotation holder and is configured to come into contact with and be separated from the first fixed contact, and a second movable contact which is held in the rotation slider and is configured to come into contact with and be separated from the second fixed contact are provided, wherein, a rotation switch mechanism which includes the rotation holder, the first movable contact, and the first fixed contact is arranged on one surface side of the circuit board, and a slide switch mechanism which includes the rotation slider, the second movable contact, and the second fixed contact is arranged on the other surface side of the circuit board, wherein, the rotation switch mechanism is configured to output a signal corresponding to at least one rotation position of the rotation holder, and when the rotation holder is set to a predetermined rotation position, the slide switch mechanism is configured to output a signal corresponding to a tilt direction of the operation shaft, wherein, the rotation switch mechanism outputs a first signal when the rotation holder is set to a first rotation position that is farthest from a rotation neutral position, wherein, the slide switch mechanism outputs a second signal corresponding to the tilt direction of the operation shaft as the operation shaft is tilted when the rotation holder is set to a second rotation position that is separated from the rotation neutral position in one direction part way to the first rotation position, wherein, the slide switch mechanism outputs a third signal corresponding to the tilt direction of the operation shaft as the operation shaft is tilted when the rotation holder is set to a third rotation position that is separated from the rotation neutral position in the other direction part way to the first rotation position; wherein a guide groove which is formed by causing an annular groove portion that extends in an annular form and a linear groove portion that extends outward at predetermined intervals to be continuous is provided on an inner wall surface of the housing, wherein, a plurality of sliding pins protrude from the rotation slider so as to cause positions of the sliding pins to be restricted by the guide groove, and wherein, the sliding pins move along the annular groove portion during rotation of the rotation slider, and the sliding pins move along the linear groove portion during sliding of the rotation slider.
