Question

I'm using D4DL/D4BL Safety-door Switches with a mechanical lock. If the solenoid power is turned ON to release the lock, the door is opened, and then the power to the solenoid is turned OFF, will D4DL/D4BL lock by itself when the key is inserted?

Answer

Yes, it will lock if you simply insert the key.
