Electronic schematic: Delayed Off Light Switch - Rated for use ...
Delayed Off Light Switch - Rated for use with incadescent loads. This is an unusual design in that it uses plain metal gate CMOS logic instead of the usual PIC or a custom chip. The 22uF capacitor charges up during one half of the ac cycle, and supplies trigger current to the triac on both halves.
