Abstract
A power plug includes a shell, input insertion plates, output power lines, a push button on the shell, and a trip assembly inside the shell for controlling electrical coupling between the input insertion plates and output power lines. The trip assembly includes a light emitting element, electrical coupling terminals, and a drive member mechanically coupled to the push button and configured to, in response to a pressing of the push button, control electrical coupling of the electrical coupling terminals, which in turn controls the electrical coupling between the input insertion plates and output power lines. The drive member includes a reflective portion that reflects a part of the light from the light emitting element to the push button as an indicator light. The dual function drive member that accomplishes both mechanical coupling and light transmission reduces the number of components. A device with an electrical control circuit is also disclosed.
