I Need A Simple Time Switch.

Recommended Posts

I need a simple switch.

Push or turn on and it is on for say 10 seconds then it turns itself off until the next push.

The exact time isn’t very important, can be a few seconds to a few minutes.

In the old days I would have tried to build one with a 555 timer but I am lazy these days.

Surely there must be a simple switch like I described for sale.

Tried the usual suspects and couldn’t find anything.

Any help would be appreciated.

Simple solution: Pnuematic Light Switch; as used for landings in flats; adjustable from 10 secs to 10 mins.

Works by air bleeding out.

Not much to go wrong!
