thanks its working..
the input is pushbutton.. so in ur attached diagram 3rd line the output must be latched...

Current rating means maximum allowable current through the component,,
Example:
Given the current rating of a cable as 10 Amperes...
It means you should use this cable for conducting current of less than 10 amperes only (for only load of less than 10 amperes..)..
if the cable is used for more...
