ABSTRACT:
A slider 13 is operated by a lever and provided with a neutral recess 23, a forward recess 24, and a reverse recess 25 which are adapted to serve as a compulsory separation means. Actuating members 16, 17, and 18 are disposed to enter the corresponding recesses and are provided with conductive plates 32, 40, and 46, respectively. Movable contacts 35, 41, and 47 are mounted on the conductive plates, whereby each movable contact is adapted to close any of the corresponding stationary contacts 36, 37, 42, 43, 48, and 49 only when each actuating member enters the corresponding neutral recess 23, forward recess 24, or reverse recess 25, while the other movable contacts are compulsorily separated from the corresponding stationary contacts.
