    摘要： Systems, methods, and apparatuses are provided in which power control relay switches may be configured to switch at or near a predetermined time during an AC cycle and/or that are configured to control a velocity of an armature of the relay switch during switching. An input power source may provide alternating current (AC) power and a voltage or current level of the AC power may be sensed. A relay controller may switch the relay switch based on a time at which the voltage or current is at or near a zero-crossing. The relay controller may be configured to close the relay switch based on when a voltage of the power input is at a zero-crossing, and is configured to open the relay switch based on when a current of the power input is at a zero-crossing.

    摘要： A device is disclosed for transmission of forces on a moving contact connecting bolt of a contact system including a switching unit with a moving contact and a further contact. The device includes an at least partially flexible conductor element for electrical connection of the moving contact connecting bolt to a connection of the switching unit and at least one first branch and a second branch. The branches are arranged for reciprocal current flow to generate an electromagnetic force. The invention the second branch is guided along and retained on a support plate firmly connected to the moving contact connecting bolt such that an electromagnetic force occurring in a short-circuit is introduceable between the first branch and the second branch for increasing a contact pressure exerted by a contact pressure spring in the moving contact connecting bolt, the support plate being slidably movable in the housing of the switching unit.

    摘要： A relay drive circuit electrically connects to an alternating current power source for driving a relay includes a zero crossing test circuit, a logic control circuit, and a switch. The zero crossing test circuit is electrically connected to the alternating current power source and is for obtaining zero crossing regions of the alternating current power source and outputting a corresponding zero crossing detect signal. The logic control circuit is electrically connected to the zero crossing circuit and is capable of receiving the zero crossing detect signal and a corresponding switch control signal. The switch is electrically connected to the logic control circuit and the relay and is switched on or off in the zero crossing regions under the control of an output signal from the logic control circuit to corresponding control and power the relay on or off.
