The vacuum tube's moving conductor is connected to the insulator, connecting rod, contact spring, and cantilever via a rotating shaft. When closing, the closing circuit energizes the closing coil via an auxiliary switch, driving the connecting rod to rotate the shaft upward, simultaneously moving the cantilever upward. This action closes the contacts within the vacuum tube via the contact spring, providing contact pressure to ensure reliable closure without bounce. During the holding state, the auxiliary switch is open, and the holding coil is energized, maintaining the contactor in the closed state. When the power supply circuit is de-energized, the contactor opens, driving the shaft downward. Simultaneously, the contact spring's and opening spring's restoring forces separate the vacuum tube contacts by a specified distance, ensuring reliable opening.
