Abstract: A power switch with an independent light-emitting chamber includes a housing, a press-key, a power assembly, at least one light-emitting unit, and a circuit board. The housing is provided therein with a partition wall that divides the interior of the housing into a first receiving space and a second receiving space. The press-key and the power assembly can be disposed in the first receiving space. The press-key can bring the power assembly into a power-off state or a power-on state. The light-emitting unit can be disposed in the second receiving space and thereby turn the second receiving space into an independent light-emitting chamber. The circuit board can be disposed in the housing and electrically connected to the power assembly and the light-emitting unit. The power switch is enhanced in safety as the partition wall keeps the light-emitting unit and the power assembly from each other and hence from short-circuiting.

Abstract: A two-points-and-one-line push-in terminal capable of secure positioning includes a terminal body and a busbar, and can be mounted in a housing to form a connector. The terminal body is formed by stamping and bending an elastic metal plate, has a U-shaped longitudinal cross section, and includes a front upstanding insertion leg, a horizontal joining foot, and a rear upstanding insertion leg. The elastic metal plate can be divided by at least two slits into at least four independent sections, each having a U-shaped slit defining a pressing spring finger and a pressing frame. The busbar can be mounted on the horizontal joining foot. An electric wire can be passed through a corresponding pair of the U-shaped slits so as to abut against the free ends of the corresponding pressing spring fingers and the busbar and be restrained in the corresponding pressing frames, which serves as the two-points-and-one-line positioning mechanism.
