ABSTRACT:
This invention relates to a multiobjective switch opening and closing apparatus which is suitable for use, for example, with a television game machine, comprising a support plate, a guide plate with a guide hole mounted parallel to the support plate, an operating lever mounted pivotably and rotatably on the support plate and reaching the guide hole, a plurality of first switches positioned between the support plate and the guide plate and installed around the operating lever, and a plurality of second switches positioned between the first switches and the support plate and installed around the operating lever. The opening and closing of the first switches are selectively carried out by the pivotal operation of the operating lever whereas the opening and closing of the second switches are selectively carried out by the rotational operation thereof, whereby the opening and closing of a number of switches can be carried out by operating a single operating lever. One or two of the first and second switches can be opened and closed simultaneously.
