3500N IP67 Waterproof Linear Actuator with Magnetic Limit Switch - 800mm Adjustable Stroke (Model 0041945-3) Choose Stroke Rod Material for Linear Actuator::Stainless Steel You can connect manual switches

You can connect manual switches

This synchronous controller is ideal for eight heavy-duty industrial linear actuators

but the stroke rods cannot be manually retracted to close the cellar door

you can connect a normally closed limit switch to terminals <TOPR> and <COM>

3500N IP67 Waterproof Linear Actuator with Magnetic Limit Switch - 800mm Adjustable Stroke (Model 0041945-3) Choose Stroke Rod Material for Linear Actuator::Stainless Steel You can connect manual switchesThis is a IP67 waterproof and low noise linear actuator with adjustable stroke and standard stroke of 800 mm. It is equipped with two external magnetic switches that can slide freely, and by adjusting the position of these two magnetic switches, the linear actuator can be controlled to work within the set stroke length. For example, for a linear actuator with a stroke of 800 mm, you can set it to move within a stroke range of 50 mm to 750 mm. The
