Abstract

Electrode sets each composed parallel electrode plates and a slider are arranged in a contact point accommodating chamber formed with wall portions of an upper case and a lower case. A lever of a knob penetrates through a slit hole in a ceiling wall. A tip end of the lever engages blocks in a box portion in the slider. The slider slides while an opening end surface of the box portion makes contact with a lower surface of the ceiling wall surrounding the slit hole. The slider presses a ball urged by a coil spring retained in the box portion press on a swing contact piece supported by a second of the electrode plates to roll thereon, thus switching a conducting state between the second electrode plate, and a first electrode plate and a third electrode plate.
