That would be annotated as "DPDT Center Off". Even Radio Shack should have them. see http://www.radioshack.cpm/product/index.jsp?productid=24431266 On Wed, 19 Feb 2014 20:18:02 +0000, George wrote: I have a doubleswitch,but it has no off position I want to reverse a linear actuator with periods of no activation. --- This email is free from viruses and malware because avast!

Connect 1 pole to - Negative and the other pole to + Positive. The actuator wire goes to the center of each switch/relay. When both are in the same position, no motion, change the state of the switch or relay depending on the direction you want it to go. RogerN |

They have forward, off and reverse functions. http://www.amazon.com/Electric-Wirel...xp_grid_pt_0_0 http://www.amazon.com/Reversing-Cont...791579-2122912 Those are just for an example, I don't know if they are suitable for your application. jsw |
