MULTI-SWITCH FOR POWER CONTROL OF PORTABLE AND MOBILE COMMERCIAL POWER SUPPLY DEVICE

摘要

The present invention is a multi-switch for power control of a portable and mobile commercial power supply device, wherein an inverter is operated only when a plug of an external power supply device to be used is plugged in, standby power consumption is fundamentally blocked and heating is reduced, long-term durability of the inverter is innovatively improved, it is possible to reduce manufacturing costs since an inverter switch is not separately provided, and it is possible to reserve a use life of the portable and mobile commercial power supply device. A multi-switch (S) is configured to control power of an inverter and an outlet to turn on the inverter only when a plug (P) integrated with an external power supply device is connected to a plug insertion port (111) provided in a portable and mobile commercial power supply device, the multi-switch (S) is configured in any one type of: an open type (100) in which a contact point is connected only when an outlet body (110) to which the plug (P) is plugged and an openable and closable outlet cover (114) are opened, and the inverter is turned on when an inverter connection portion (102) is connected through trigger power application; and a pressurization type (200) in which a contact point is connected by pressurization at the time of plugging the plug (P), and the inverter is turned on when an inverter connection portion (202) is connected through trigger power application.;COPYRIGHT KIPO 2015
