Why not just use a regular timeswitch to switch the coil of a regular contactor?

Because I have a stop button and if A1 is constantly fed from 8.00-9.00 I've no way of deactivating the coil? Thanks

Thanks MDJ, have you any expire acne using these timers can I put two times into them? And does the timer just reset when it gets to 0? Thanks

? Feed the contactor from the stop circuit.

By putting a contactor in like you mentioned in op the stop circuit could be overridden

you can set those timers to any amount of time you want, we built a photography film developer out of an old record player connected to one of those, it would spin the disk for a few seconds then stop then respin etc etc, so it should do what you require it to. A trip to your local maplins for a chat with the staff there may also help.

You could use a din rail impulse contactor/relay and a din rail pulsed timeswitch....each time the impulse contactor get a 1 sec pulse from the timeswitch, it changes state, ie 8am 1 sec pulse, impulse contact stays on until another 1 sec pulse is recieved, as so on.....you over ride switch will be breaking feed from impulse contactor, to main operating contactor.
