Apologies if I'm asking dumb questions, but the last time I needed to do anything like this was at school 20 years ago and I can't remember how!
I have a circuit which is set up so that when a button is pressed, a relay is tripped for half a second which triggers a (mains) light. I'm using a simple timer circuit which Maplin sell to do this. I've used the circuit for many things, it's simple, it works, and it doesn't break. So far so good with that, however I need to be able to add a delay, so that 10 seconds or so goes by before the circuit can be tripped again. Otherwise it is possible to hold down the button so the light stays on.
I either need something I can add to my existing circuit, or a completely new circuit which can replace my trusty timer circuit. I would also like the illuminated button to go out during the 10 seconds delay if possible.
Please help, I'm sure I used to know how to do this and it's driving me crazy!
Thanks
