preasure pads

[firemonkey]

I am planing to make a installation of reclaimed materials but i want to make the pieces of art interactive with the viewers, so i have decided to use old fairy lights but I want the viewers to be able to activate them, so I was thinking about preasure pads? but dont know much about them or where i can get them, so if anyone as any ideas please let me know.thanks

If you wire them up to "time lag" switches you can set the time from between 10 seconds and ten minutes.

Google "Time lag switches" for more info.....
