Abstract
A contactor includes a contact portion and an actuation portion. The contactor further includes a keeping portion. The keeping portion includes a capacitor structure and uses an electrostatic force between opposite plates of the capacitor structure to keep the contact portion in a contact state or a disconnection state. The electrostatic force generated by an electrostatic latch is used to keep the contactor in a switched-to static state. The contactor has reduced energy consumption in the static state, is convenient to manufacture, and has a low cost.
