A base on which two single push-on switches are provided is a part of a wiring board of an electronic device to be used, and a supporting portion for rotatably and vertically moving an operation button is used for the electronic device to be used. The multi-circuit push-on switch according to any one of claims 2 to 7, wherein the switch is formed integrally with the case. 9. The multi-circuit push-on switch according to claim 1, and two single push-on switches within a predetermined time by pressing an operation button of the multi-circuit push-on switch. Multi-circuit push-on provided with switching recognition means using time measuring means for processing as another electric signal different from the electric signal when either of the single push-on switches is turned on when turned on Electronic equipment using switches. 10. A menu including a plurality of selection items displayed in a main body display portion in a predetermined arrangement relation, and pressing a predetermined range on an upper surface of an operation button to select one of two single push-on switches. By turning on only one of them, an electric signal indicating the first or second state is generated so as to move the plurality of selection items in a predetermined direction, and the two single units on the upper surface of the operation button are generated. By pressing a predetermined range on the upper surface of the intermediate portion of the push-on switch to simultaneously turn on the two single push-on switches, a third state is shown so as to determine the selection item after the movement. 10. An electronic device using the multi-circuit push-on switch according to claim 9, wherein the electronic device generates an electric signal.
