Claims (1)

[Claims for Utility Model Registration] (1) A plurality of mode switching buttons that control switching of corresponding mode switching switches to predetermined modes by pushing and locking, a return actuator that returns all of the mode switching buttons, and the mode switching a return button that is placed apart from a group of buttons and drives the return actuator when pressed; and a switching transistor that is turned on only when one of the mode change buttons is in a pressed state. A multiple changeover switch device, characterized in that the return actuator is energized and driven via the switching transistor by pressing the return button. (2) In the device described in claim (1) for utility model registration, each mode selector switch has a normally open contact, a normally closed contact, and a common contact, and the normally closed contact of each switch and the common contact are connected in series, A multiple changeover switch device characterized in that a base of a switching transistor is connected between a normally closed contact end of the mode changeover switch group and a power supply. (3) A multiple changeover switch device according to claim (1) or (2) of the utility model registration, characterized in that the return actuator is connected in series between the collector end of the switching transistor and the power source. . (4) In the device described in utility model registration claim (1) or (2), the return actuator is connected in parallel to the switching transistor and the power supply,
A multiple changeover switch device characterized in that it is activated by a relay that is turned on in conjunction with a switching transistor. (5) In the device described in utility model registration claims (2) to (4), a mode display indicator connected to a normally open contact of each mode selector switch, and a mode display indicator that lights up when the mode selector switch is completely off. A multiple switch device characterized by comprising a return mode display indicator.
