@Leroy1618 hey man, do you want to buy a light switch like this thats touch to turn on?? email me jacobstar@hotmail.com and ill help you and show you pics
-
if anyone wants a house voltage 100-250v touch screen light switch message me and ill point you where to buy them
-
@gobrownj could you put up some link as to where you bought the stuff and how to assemble. i would love to make these in my house..
-
Are you using 555 timer chips for this switch?
Can someone explain how this works? (I know that the human body is a "capacitor" with 30-50 pico farrad, this might be a reason for this switch)
-
nice....
its supports 30~60watts lamp ???
-
Is it possible to get the schematic for this by any chance?
-
@gobrownj i like the capacitance touch switch, can u please mail me the schemetic & part list on mckhedekar@yahoo.co.in thanking u.............................

@gobrownj do you have a schematic?
-
really nice design. schematic my any chance?? Thanks a bunch. -Joe
Thats not capacitance, that's a piezo!

The principle in which the finger is detected is based on capacitance as the plastic plate is non-conductive. A piezoelectric speaker is used to provide audio feedback in addition to serving as an electrode sensing the finger. This can be done without the piezoelectric speaker as well.
