Hello friends,

I am using my household device i.e. working on AC. It contains its own switch for on and off. Now i want to use touch pad only for switch on the device and switch off the device. what are easiest possible solutions?

thanks in advance...

A simple capacitive plate would work, but be sure to isolate the AC somehow. A wall wart (for DC power) such as an old phone charger (they tend to be small) and a SSR (Solid State Relay) comes to mind. I might sketch something up as a starter idea, but it would be untested.

I take it you want a touch on/touch off switch? What kind of current requirements are you thinking about? I am assuming USA standards, 120VAC 10A max.

ok.

right now my current requirement is 1A to 5A but later it will increase to 16A.
voltage is 230V (as per Indian standard).

The current requirements do present a small problem, but only with heat sinking. SSRs do have current limits (though you can by ones that are quite large) and will get hot if they are carrying a lot of current. Do you like to experiment?
