Fig. 1 is structural representation of the present utility model, as we can see from the figure, this power switch circuit system, comprise electronic switch 7, the power end of electronic switch 7 connects power supply 5 with power line 6, output connects controlled device 8, and end of convert connects signal controller 1 with signal wires 2, and signal wires 2 is drawn delay capacitor C
110, delay capacitor C
110 other end ground connection 12, the controlled circuit input capacitance C that electric wire is connected with ground connection 12 that is connected of electronic switch 7 and controlled device 8
29; Described signal wires series resistance R
111; The delay capacitor C of described power line 6 and signal wires 2
1Use electric wire 4 contact resistance R between 10 the leading point
23.
The utility model is when the switching signal of electronic switch 7 drags down control end, because delay capacitor C
110 in resistance R
2Be charged to power supply under 3 the effect, the grid voltage of electronic switch 7 can not be drawn as low level quickly, thus can be limited in lower level through the electric current of electronic switch 7, along with delay capacitor C
10 position is slowly forgotten about it in 10 discharge, the grid voltage of electronic switch 7, and controlled circuit input capacitance C
29 voltage also slowly is charged to power supply 5 by less electric current, and last electronic switch 7 is opened fully.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme that is comprised of above technical characterictic combination in any.
