Hello,

I am working on a project that requires the following:

A NO button is pressed causing the linear actuator to travel forward, until hitting a NC limit switch. The actuator then travels backwards until it hits a another NC limit switch, causing it to stop. I have been experimenting with different circuits and have attached one diagram. If you look at my circuit drawing my problem is that when limit 1 is hit causing reversal the limit switch will close again causing continuous forward backward travel. Any comments are highly appreciated. Both relays are DPDT. Thanks

 

You have an even bigger problem. In the circuit shown, no current will ever pass through the motor.

 

Looks like I have attached both leads of the right relay to -12 V. Attached should be the corrected one. Thanks

 

It looks like you may need to put some kind of latch function across the reversing limit switch, otherwise as soon as the traveler moves off the switch, it would go back into the forward direction and just bounce back and forth.

 

Try this:

 

Thanks a lot wookie.
