Electronic Door Activated Socket

[maxtate]

Hi, I was hoping for any advice that could help me build my door activated socket project! I'm trying to build a socket that turns off when that door is opened. This is for a friends son who goes to a boarding school. He always says how he studies after the 'curfew' and gets told off if a teacher checks his room. I am trying to create a device which he can plug his lamp into and then when the door opens *teacher walks in* the socket will turn off, the lamp will go out, and he will look like he's asleep! Any ideas or help would be gratefully received. I have some basic knowledge of electronics however I'm no whizz!

Thanks, Max Tate.

ps. I want to keep expenditures under £15 and I have a 3 week deadline!

Hi,

You need a normally open push-button compatible with the main voltage and a bit of mechanic to adapt it to the door. It's to be wired up like any switch-bulb circuit.

Thanks again, Max Tate.

No, what you need is a momentary push button, not an ON/OFF switch who lock the contact.

For someone with your level of knowledge to mess with mains wiring at a boarding school sounds like criminal negligence to me.

Hi Bob, I do understand the risks and i have a few electrician friends who i will get to check over the wirings ect... when I'm done. Hopefully all should go well! Olive thanks for the advice, Is this a suitable... http://www.sourcingmap.com/22mm-no-...gn=ukfroogle&gclid=CMe-48GshLsCFW_JtAod02gAwQ product, 240v and push to lock and stop. Then wire and exention lead cable into this, and back down to sockets?

Hi,

yes that's a good model of push button. For the wiring it' s all depend of the existing installation and if you can easily add wire in the existing tubing or add a new tube or....better to check that locally with your electrician friend, and yes working on the main voltage must be done CAREFULLY !!!
