A combined operation type switch device, comprising: an upper case in which a pair of first guide grooves (112a and 112b) having symmetrical shapes are formed in opposing inner surfaces thereof; a lower case which is joined to a lower portion of the upper case; a holder in which a pair of first guide protrusions (131a and 131b) respectively inserted into the first guide grooves (112a and 112b) are formed in opposing outer surfaces thereof and second guide grooves disposed in a vertical direction are formed in opposing inner surfaces thereof, and which is held inside the upper case via the first guide protrusions (131a and 131b) inserted into the first guide grooves (112a and 112b) so as to rotate left and right; a slider which is accommodated inside the holder, has second guide protrusions inserted into the second guide grooves formed in opposing outer surfaces thereof to slide in the vertical direction with respect to the holder, and is provided to rotate in left and right directions; a wheel button which is accommodated inside the slider and is rotatably held, and of which a part penetrates through the upper case to be exposed to an upper portion so as to enable a user to perform a three-way (center, left, and right) pushing operation and a rotating operation; an encoder which is joined to a left-hand end of a drive shaft of the wheel button, detects a rotational direction and a rotational amount of the drive shaft during rotation of the wheel button, and outputs an electrical signal corresponding thereto; and a circuit board which is fixed to the lower case, includes a plurality of electrodes in an upper surface thereof, and includes a plurality of contact switches at positions where the electrodes are respectively provided so as to allow the electrodes to be selectively connected by a vertical sliding motion of the slider interlinked with the three-way pushing operation of the wheel button and a left and right rotating motion of the slider and the holder. an upper case in which a pair of first guide grooves (112a and 112b) having symmetrical shapes are formed in opposing inner surfaces thereof; a lower case which is joined to a lower portion of the upper case; a holder in which a pair of first guide protrusions (131a and 131b) respectively inserted into the first guide grooves (112a and 112b) are formed in opposing outer surfaces thereof and second guide grooves disposed in a vertical direction are formed in opposing inner surfaces thereof, and which is held inside the upper case via the first guide protrusions (131a and 131b) inserted into the first guide grooves (112a and 112b) so as to rotate left and right; a slider which is accommodated inside the holder, has second guide protrusions inserted into the second guide grooves formed in opposing outer surfaces thereof to slide in the vertical direction with respect to the holder, and is provided to rotate in left and right directions; a wheel button which is accommodated inside the slider and is rotatably held, and of which a part penetrates through the upper case to be exposed to an upper portion so as to enable a user to perform a three-way (center, left, and right) pushing operation and a rotating operation; an encoder which is joined to a left-hand end of a drive shaft of the wheel button, detects a rotational direction and a rotational amount of the drive shaft during rotation of the wheel button, and outputs an electrical signal corresponding thereto; and a circuit board which is fixed to the lower case, includes a plurality of electrodes in an upper surface thereof, and includes a plurality of contact switches at positions where the electrodes are respectively provided so as to allow the electrodes to be selectively connected by a vertical sliding motion of the slider interlinked with the three-way pushing operation of the wheel button and a left and right rotating motion of the slider and the holder.
