Abstract: A power interrupter device includes a solid-state bidirectional switch and control circuitry to control the solid-state bidirectional switch. The bidirectional switch is connected between input and output terminals of the power interrupter device. The control circuitry includes driver circuitry and fault detection circuitry. The driver circuitry generates a regulated direct current (DC) voltage using current drawn from an input power source applied to the input terminal and applies the regulated DC voltage to a control input of the bidirectional switch. The fault detection circuitry is configured to sense a level of load current flowing in an electrical path between the input and output terminals, to detect an occurrence of a fault condition based on the sensed load current level, and to short the control input of the bidirectional switch to place the bidirectional switch in a switched-off state, in response to detecting the occurrence of a fault condition.

Abstract: A universal light string lamp bypass device is comprised of a plug and a resistor. The plug is shaped and sized to releasably fit within the base of a lamp assembly. The plug encapsulates the resistor with the resistor leads extending from the bottom end of the plug. When the encapsulated resistor is inserted into a lamp base it can be electrically connected to the lamp socket terminals. The impedance of the resistor substantially matches the impedance of an operating lamp within a lamp socket of the light string. Most lamp bases have a standard configuration for receiving a lamp. This device fits within a lamp base after the lamp has been removed. A section of a light string may be darkened by replacing its lamps with the device. A typical use is for the darkening of a section of a light string connecting two decorated bushes.
