Description

Input device Technical Field The present invention relates to an input device. Background Patent document 1 discloses a two-stage operation switch device for operating a power window, which is capable of turning on a first switch and a second switch in two stages according to a rotational operation position of an operation knob. Prior art literature Patent literature Patent document 1 Japanese patent No. 3810920 Disclosure of Invention Problems to be solved by the invention However, the technology disclosed in patent document 1 is a structure in which the return means (dome portion) of the rubber sheet is pushed obliquely by tilting the push rod, and therefore the dome portion is pushed obliquely downward and is deformed elastically while being twisted. Therefore, fatigue tends to accumulate in a part of the dome portion as compared with a structure in which the dome portion is pressed straight downward. Further, the dome portion is partially broken by accumulated fatigue, and thus the life of the rubber sheet may be shortened. Means for solving the problems An input device according to one embodiment includes a housing, an operation knob supported by the housing and rotatable by receiving an operation force from an operator, a cam member provided to be swingable in a direction intersecting a rotation direction in which the operation knob rotates, and configured to perform a first operation in a swinging manner when the operation knob rotates in a first angle range, and to perform a second operation in a swinging manner when the operation knob rotates in a second angle range in a connection with the first angle range, a base plate provided in an interior of the housing, a first switch provided on the base plate and turned on in response to the first operation of the cam member, and a second switch provided on the base plate and turned on in response to the second operation of the cam member, and configured to automatically return the operation knob by a restoring force from the first switch and the second switch when the operation knob is released from the operation force, wherein the input device has a first switch provided on the base plate and a second switch which presses the cam member in a direction perpendicular to the first switch and a second switch, and presses the cam member in response to the first switch and the second switch.
