Title:
SWITCH DEVICE
Document Type and Number:
Japanese Patent JP2022052457
Kind Code:
A
Abstract:
To provide a capacitance-type switch device which offers an operational feeling.SOLUTION: The switch device comprises: a knob 10, provided with moderation parts 11e and 11f, which is operated by an operator; a housing 20 which swingably supports the knob 10; a detection electrode 31, provided on the knob 10, which detects the approach or contact by a finger of the operator; a terminal electrode 32 which is provided on the moderation parts 11e and 11f, and which outputs an electric signal of the detection electrode 31 from the knob; an elastic electric connection body 40 which has elasticity for applying biasing force to the moderation parts 11e and 11f, and which is a conductor that is electrically connected to the terminal electrode 32 in a state brought into contact therewith by the biasing force; and a control part 70 which is electrically connected to the detection electrode 31 via the elastic electric connection body 40 so as to detect the capacitance of the detection electrode 31.SELECTED DRAWING: Figure 4
