Remote Control Dual Linear Actuators

Do you have access to the limit switches where you can wire them yourself? I have a system where I use the limit switches to drop out the run relay. The run relay is activated when the direction relay changes from energized to de-energized or vice versa. The direction relay is 3PDT, the run relay is SPST. The direction relay is controlled by a toggle switch. You could use an X-10 to provide the toggle switch function. That would initiate a cycle where the acutators go from fully extended to fully retracted (or vice versa), then stop. If you want the capability to stop somewhere in between, then a single X-10 driving a DPDT relay won't do it.

I don't have to stop it in the middle and so my basic dpdt relay would work. I've never tried this sort of application and am very much self taught. I did manage to create a PWM to use as a thermostat which I connected to a couple of TEC's but I'm not so familiar with using relays. On another thought, would an h-bridge allow me to stop in the middle if I wanted? I don't have to use an x-10 module (I have some lying around) I just wanted something simple that would allow remote/ wireless control of the circuit.

thanks again, james

Here's how mine is wired:
