Technical Field
[0001] The utility model relates to the field of smart home, in particular to an intelligent switch panel. Background Art

At present, there are two main ways to electrically connect the sub-circuit board and the main circuit board.
[0003] The first electrical connection method between the existing auxiliary circuit board and the main circuit board is a pin header and a female header connection. However, the use of a pin header and a female header for connection will cause the pin header and the female header to hinder the movement of the multi-function key board, causing an unbalanced force problem for the multi-function key board that is matched with the auxiliary circuit board.
