摘要： An illuminated electrical load control is provided for controlling electrical power to a light-emitting diode (LED) lighting load. The load control includes a wall-box mounted housing, and an electrical switch assembly disposed at least partially within the housing. The switch assembly includes an actuator coupled to transition the switch assembly between an ON state, where AC current flows to the LED lighting load, and an OFF state, where current is interrupted from flowing to the LED lighting load. Further, the load control includes an illumination assembly with an indicator light to illuminate, at least in part, the load control when the switch assembly is in OFF state, and a current-limiting circuit connected across terminals of the switch assembly, and configured to limit leakage current through to the LED lighting load to below an activation current of the LED lighting load when the switch assembly is in the OFF state.

摘要： Operating an electrical load controller includes, in one aspect, predetermining a duration of time based at least in part on a frequency of an alternating current (AC) waveform, the alternating current (AC) waveform oscillating though full cycles, each full cycle comprising a positive half cycle and a negative half cycle; selecting a detection window of time equal in duration to the predetermined duration of time, the selected detection window extending from a selected first time to a selected second time and straddling an expected time of a next zero-crossing of the AC waveform; monitoring a zero-crossing signal for a zero-crossing indication, of the next zero-crossing, occurring within the selected detection window; ascertaining a time of the next zero-crossing based on the monitoring; and selectively controlling a supply of AC power to a load, wherein the controlling uses the ascertained time of the next zero-crossing of the AC waveform to fire a switching circuit of the electrical load controller. Additionally or alternatively, operating an electrical load controller includes, based on a desired load level setting of the electrical load controller, determining a firing angle, of an alternating current (AC) waveform, at which to fire a switching circuit of the electrical load controller to selectively control the switching circuit to conduct a supply of AC power to a load, the firing angle corresponding to a firing delay time, after zero-crossings of the AC waveform, at which to fire the switching circuit; selecting a control signal pulse duration, the control signal pulse duration being a duration of time for a control signal to be held in an ON state to latch the switching circuit to conduct the supply of AC power to the load, wherein the selecting the control signal pulse duration comprises selecting, for the control signal pulse duration, and based on the determined firing angle, between: (i) a fixed duration of time that begins at the firing delay time and ends after the fixed duration of time; and (ii) a variable duration of time that begins at the firing delay time and ends at a preset unlatch time of the AC waveform; and controlling the supply of AC power to the load based on the selected control signal pulse duration, wherein the controlling holds the control signal in the ON state for the selected control signal pulse duration in selectively controlling the switching circuit to conduct the supply of AC power to the load. Alternatively, in some aspects, operating an electrical load controller includes based on a desired load level setting of the electrical load controller, determining a firing angle, of an alternating current (AC) waveform, at which to fire a switching circuit of the electrical load controller to selectively control the switching circuit to conduct a supply of AC power to a load, the firing angle corresponding to a firing delay time, after zero-crossings of the AC waveform, at which to fire the switching circuit; detecting whether a voltage sag is present in the AC waveform; selecting a control signal pulse duration, the control signal pulse duration being a duration of time for a control signal to be held in an ON state to latch the switching circuit to conduct the supply of AC power to the load, wherein the selecting the control signal pulse duration comprises selecting, for the control signal pulse duration, and based on the determined firing angle, between: (i) a fixed duration of time that begins at the firing delay time and ends after the fixed duration of time; and (ii) a variable duration of time; wherein the selecting is based further on determining that the firing delay time is less than a first threshold delay, and on the detecting whether the voltage sag is present in the AC waveform; and controlling the supply of AC power to the load based on the selected control signal pulse duration, wherein the controlling holds the control signal in the ON state for the selected control signal pulse duration in selectively controlling the switching circuit to conduct the supply of AC power to the load.

摘要： A paired simplex fiber optic connector assembly comprises a clip that holds two simplex LC connectors together to yield a duplex connector that can be plugged into a duplex adapter. In some embodiments, the two simplex connectors are held in place by rails formed on both sides of the clip. In other embodiments, a side arm is formed on each side of the clip, the side arm comprising a hub that extends from the clip and a non-circular flange formed on the end of the hub. The flange is configured to engage with channels formed on the sides of the simplex connectors, thereby holding the simplex connectors in place. The simplex connectors are attached to the clip by rotating the connectors about the flange, thereby engaging the channels with the flanges.

摘要： An electrical disconnect switch including an over-rotation protective feature to protect the load switch from damage is disclosed. The electrical disconnect switch may include an enclosure, a load switch, and a handle assembly coupled to the load switch. The disconnect switch may include a detent between the handle assembly and the load switch so that during excessive rotation or torqueing the handle assembly is permitted to decouple or break-away from the load switch to prevent excessive stress from being transferred to the load switch and thus prevent any damage to the load switch.

摘要： A telecommunications enclosure having a door hingedly attached to a chassis. The chassis has a first through-hole configured to have at least one patching panel installed therein. A different enclosure, like the telecommunications enclosure, is mountable on the door. The door is rotatable relative to the chassis between closed and open positions when the different enclosure is mounted thereto. The door allows access to an interior of the chassis when the door is in the open position. The chassis and/or the door may have a second through-hole configured to allow a telecommunications cable connected to the at least one patching panel to pass therethrough and exit the interior of the chassis.
