So Boncuk, I'm confused. I can understand a 14DIP being too big, but a SOT23 might(?) be OK otherwise, and an R/C solution is still too big? Seems like you could get an R, C and a D/Q into about the footprint of an 8DIP, no? Especially if you can mount the resistor vertically rather than flush.
On another note, you could vandal-proof the switch by putting it very, very, very close to the hot 220VAC line. They'll get a big-ass zap the first (and last) time they abuse the switch. Worker protections probably aren't real strong in Thailand, so you're operating within specified tolerances.
