I set up a linear actuator on a timer with a relay and 12 Volt 5 Amp battery exactly like to project you show on your site. It worked like a champ for about 2 months the stopped. I thought maybe the battery need a recharge but that wasn't the issue. When the switch opens and remains open the red light on top of the relay remains on. I keep the door open for about 4 hours in the morning then it closes. It opens again for about 4 hours before dusk then closes again until the next morning. My concern is that the red light on the relay is indicating that the switch is on continuously sending electricity to the actuator. After 2 months it just fried the actuator. I took apart the actuator and it looks like its brand new with no black spots on the copper wires. I'm hoping I just have a bad actuator.
