wherein the base includes a remote device, and the remote device has at least one remote linkage rod ( 9 ), and the function rotating member ( 3 ) has a remote linkage rod contact wall ( 3 D) and a remote linkage notching ( 3 H), and when the function rotating member ( 3 ) is situated at the first position, the remote linkage rod ( 9 ) is pressed down by the remote linkage rod contact wall ( 3 D), and when the function rotating member ( 3 ) is rotated from the first position to the second position, the function rotating member ( 3 ) is rotated from the remote linkage rod contact wall ( 3 D) to the remote linkage notching ( 3 H) with respect to the point of action of the remote linkage rod ( 9 ) to release the remote linkage rod ( 9 ).

2. The surge protector of claim 1 , wherein the remote device has a seat ( 13 ), a micro switch ( 15 ), at least one slider spring ( 16 ) and at least one remote linkage rod spring ( 17 ), and the seat ( 13 ) has a slide slot ( 13 A), a slider ( 14 ), at least one slider spring ( 16 ), and at least one spring placement hole ( 13 D), and the micro switch ( 15 ) is installed in the seat ( 13 ) and disposed under the slider ( 14 ), and the remote linkage rod spring ( 17 ) is sheathed on the remote linkage rod ( 9 ) and installed together with the remote linkage rod ( 9 ) in the spring placement hole ( 13 D), and the slider ( 14 ) is installed onto the slide slot ( 13 A), and the slider spring ( 16 ) has an end coupled to the slider ( 14 ) and the other end abutting against the seat sidewall ( 13 E) and when the function rotating member ( 3 ) is situated at the first position, the remote linkage rod spring ( 17 ) is situated at a maximum compression status, and an end of the slider ( 14 ) is stopped by the remote linkage rod ( 9 ) at an end of the slide slot ( 13 A), and the slider ( 14 ) has no action on the micro switch ( 15 ), and when the function rotating member ( 3 ) is situated at the second position, at least one of the remote linkage rods ( 9 ) pushes the slider ( 14 ) to move along the slide slot ( 13 A) under the pushing effect of the remote linkage rod spring ( 17 ), so that the slider ( 14 ) presses the micro switch ( 15 ).

3. The surge protector of claim 2 , wherein the remote linkage rod ( 9 ) has a driving slope ( 9 A), and the slider ( 14 ) has a driven slope ( 14 A), and when the function rotating member ( 3 ) is situated at the first position, the driven slope ( 14 A) of the slider ( 14 ) is stopped by the driving slope ( 9 A) of the remote linkage rod ( 9 ), and when the function rotating member ( 3 ) is rotated to the second position, the driving slope ( 9 A) pushes the driven slope ( 14 A) to move the slider ( 14 ) along the slide slot ( 13 A), so as to press the micro switch ( 15 ).
