Title: quiet alternative to relays

look for a "solid state relay".  It interfaces like a relay, but internally it's a semiconductors, so no moving parts.

hi

Conrad (http://www1.uk.conrad.com) is a big supplier in the UK and the EU.. they have an 8A 220V SSR for 8 pounds...Part no.: 168130 - 62

You can also look for local places, which are sometimes cheaper. Just get out your yellow pages and look for "electronic components" and give them a call and ask if the have solid state relays.
