a hidden switch

yeah that was my first thought of what to have, but where would it go? and is a hidden switch really safe and realistic?, because i have to make out that i am producing this alarm system for a company.

How about punching a few holes into an old credit card and building a simple reader with micro switches or opto-couplers?

Regards, Mike

It's like a KEY.. a punch card reader.

punch some holes (randomly) in a card. the reader has a number of light emitter/detector combo. when the card is inserted into the reader , the light can pass excat thru the punches.
hpe u understand

properly constructed using discret components , it should be around the size of a rfid card reader

Look at the Owl schematic on my site. It uses an iButton as a key. I have mine on a watch.

u can use RF remote control similar to those used in garage but with little more security

rancid rock · 10th March 2006, 10:06 PM

yeh, but would that be small and simple?

Mike, K8LH · 10th March 2006, 11:55 PM

You mentioned a keypad in your first post and I think that has thrown us all off...

Please tell us 'exactly' what you're lookin' for (dimensions perhaps)?

u just need two switches an encoder and a transmitter and this is very simple and u can get ready made moduel and keychains remote with their corresponding reciever,
search google for rf keychain remote and u will hit the right place.

it seems that ur concerned abt size rather than complexity or security of device.
