When the coil is energized, the iron core attracts the armature and the support plate to move down, and the contact points are turned on or off instantly. The piston rod and the lever slowly decrease due to the influence of the blocking nylon. After a certain period of time, the piston rod decreases to a certain position, and the delayed action contact is pushed by the lever to act, which is in an open state, while the moving contact is closed.
