Inquiry (采购产品): need some help finding the right actuator I need a 12 or 24 volt actuator that can be pushed back when the power is off, and deliver about 40 or 50lbs of push when the switch is on. I don't know alot about actuators but I am worhing on a new saftey device for electrical systems that will turn off the breaker or switch gear( commercial buildings) when the switch is on, but have the ability to flip the breaker, or switch back on when the power needs, or is safe to be turned back on. thank you for your time.
