If you wish to explore your compressor pressure switch, and I do recommend that you make yourself familiar with what is inside, make sure first that the compressor power supply is unplugged then go ahead, remove the cover. You want to be sure the power is off as there are live power connections inside the lid.
Discs are sometimes collected at some local recycling centres. To find out where your nearest recycling facilities are, use our handy Recycling Locator tool. Check local CD/DVD recycling. VHS tapes and cassettes are now rarely accepted at recycling centres and are generally sent to landfill. A company called Tip Top Media currently accepts old tapes for disposal but there may be a charge for this so please contact them for more information.
ACT employs adults with disabilities to recycle electronics, including VHS tapes. As the market dwindles, they are just about the only VHS recyclers left who do not charge a fee. And if you happen to be in the market for blank VHS tapes, ACT tapes are cheap and as good as new. (For this and other tough recycling quandaries, you can also check 1800recycling.com and earth911.com to see if you have local alternatives.)
