A COMBINED CONTROL TYPE SWITCH CAPABLE OF GENERATING A PULSE SIGNAL BY A ROTATING OPERATION OF A ROTOR, AN ON/OFF SWITCHING SIGNAL BY AN INCLINING OPERATION OF A STEM AND AN ON/OFF SWITCHING SIGNAL BY A PUSHING OPERATION OF THE STEM. IN THE COMBINED CONTROL TYPE SWITCH, A CIRCULAR OPENING 9 IS MADE IN A CENTRAL PORTION OF A ROTARY SWITCH 1 FOR GENERATING THE PULSE SIGNAL BY THE ROTATING OPERATION OF A ROTOR 7, AND A CIRCULAR HOLE 23 IS MADE IN TURN KNOB 2 INTEGRATED WITH A SHAFT SECTION 18 OF THE ROTOR 7, AND FURTHER A TERMINAL 17 OF THE ROTARY SWITCH 1 IS SOLDERED TO A LAND OF A PRINTED-CIRCUIT BOARD 5. FURTHER, A MULTI-WAY SWITCH 3 IS DISPOSED IN THE OPENING 9, AND ITS TERMINAL 33 IS SOLDERED TO A LAND OF THE PRINTED-CIRCUIT BOARD 5. THIS MULTI-WAY SWITCH 5 IS COMPOSED OF A HOUSING 24 INCORPORATING ONE CENTRAL TACT SPRING 25 AND FOUR CIRCUMFERENTIAL EDGE TACT SPRINGS 26, A FIRST STEM 27 SUPPORTED BY THE HOUSING 24 TO BE INCLINABLE, A SECOND STEM 28 SUPPORTED BY THE FIRST STEM 27 TO BE MOVABLE VERTICALLY, AND A CAP 4 FIXED TO AN UPPER END PORTION OF THE SECOND STEM 28 TO BE EXPOSED WITHIN THE CIRCULAR HOLE 23 OF THE TURN KNOB 2.(FIG. 3)
