Abstract: A remote switching system for electronic switches in a cabinet provides an actuator assembly communicating through a flexible cable with a door handle. The actuator assembly on the electronic switch provides a rotatably captive threaded fastener holding the sheath of the flexible cable to the actuator assembly allow ring a simple single-point tuning of the actuator operation. This tuning may be facilitated by a visual scale showing relative positions between the actuator assembly and an internal slider communicating with the operator of the electronic switch.

Abstract: One embodiment describes a method that includes determining, using a control circuitry, temperature of a switching device before a make operation by applying a measurement current to an operating coil of the switching device, wherein the measurement current is insufficient to make the switching device; and determining voltage at the operating coil when the measurement current is applied, in which the voltage at the operating coil is directly related to the temperature. The method further includes determining, using the control circuitry, when to apply a pull-in current to the operating coil to close the switching device based at least in part on the voltage at the operating coil, such that the switching device makes at a desired time.

Abstract: One embodiment describes a method that includes, when a motor is disconnected from a power source: starting, using a control circuitry, a counter at a first voltage zero-crossing by either a source voltage or a back electromotive force generated by the motor; stopping, using the control circuitry, the counter at a next subsequent second voltage zero-crossing by either the source voltage or the back electromotive force; monitoring, using the control circuitry, a trend in counter values; and instructing, using the control circuitry, one or more switching devices to reconnect the power source to the motor after a local minimum in the counter value trend such that the source voltage is leading the back electromotive force.
