Abstract (en)
According to the invention, in a switch unit, the dust resistance of a switch portion is ensured by an electromagnetic wave shielding member and an operation sense is hardly impaired. An electrical connection between a conductive portion of the electromagnetic wave shielding member and a grounding terminal is conducted surely and easily. A plate-like body 20 has a stationary electrode and a movable electrode 36 in a switch portion 30. The movable electrode 36 is configured by a snap plate. An electromagnetic wave shielding member 50 is overlaid on the plate-like body 20. The electromagnetic wave shielding member 50 is configured by a laminated member having a base layer 51 formed by a polyethylene terephtalate film, and an electromagnetic wave shielding layer 52 formed by an aluminum thin film. The switch portion 30 is covered by the electromagnetic wave shielding member 50. The electromagnetic wave shielding layer 52 of the electromagnetic wave shielding member 50 is electrically connected via an electrically conductive coating composition 60 with a grounding terminal 40 formed on the plate-like body 20. <IMAGE>
