a second fixed contact group including a plurality of fixed contacts formed on said printed wiring board; and
a changeover member provided with first and second moving contacts corresponding to said first and second fixed contact groups and which are disposed movably inside said casing;

Abstract
A switching device is provided which comprises a casing, a printed wiring board disposed inside the casing, a plurality of fixed contacts formed on the casing, and a plurality of moving contacts for making an electrical connection or disconnection between said plurality of fixed contacts. Since many fixed contacts are not only disposed on the printed wiring board but also on the casing, the printed wiring board can be designed compact. Also the plurality of fixed contacts disposed on the casing has such a form of a terminal as to be electrically connectable to motors and a power source as well as to a connector extended to the switching device. Therefore, the number of places to be soldered for electrical connection between many fixed contacts, motors and power source can be reduced.
