    You can also accomplish this with the just the 2-cycle timer and the limit switch. No extra relay.

      The relay is required to stop the motor. Otherwise, the inertia will push past the limit switch and keep going.

      @@ERGMIAMI So you are using it to power brake the motor? I had thought of that when typing the first comment. However I could not get a clear view of the wiring to the relay, so I could not trace what you are doing with it (how you are using it). Would you give a quick overview?
      I also forgot to mention that using just the timer and the switch it is still possible brake the motor and very easy to do so. Using a schottky diode, across the motor leads, will very effectively brake the motor. That is assuming that the polarity is never going to be reversed, since the switch is not laid out for that and it doesn't look like it would be needed. Of course, I do not know what the end function/product is and its parameters. In any case when the EMF collapse, the back EMF occurs and the polarity reverses. The diode will let power flow in the reverse direction and it brakes the motor.
      BTW I you would use octal relays and their sockets, a least in the testing phases, you will save a lot of time and effort in the wiring. Same thing with the timer. I notice that you have, what looks to be a counter on the table, so I know you know the value of using counters and timers that are of that style and use a socket. If the end product needs to be panel mounted, those timers, counters and some relays can easily be panel mounted just like the counter on your bench.
      I also recommend that if you do more of these great videos that you make a "testing panel" with a DIN rails and an angled mounted surface.
