Abstract
A switch including an insulative plastic case having a cavity formed therein, a metal cover joined to the case to cover over the cavity, and a switching contact section contained in the cavity. In this switch, a surface of the cover opposed to the case has an insulative film formed on at least a region of the surface facing to the cavity. The switch can prevent externally-originated static electricity from adversely affecting the switching contact section to protect a circuit section of a device connected to the switching contact section.
