Abstract: A waterproof structure of a handheld lamp installed at a power socket includes a base having an accommodating space, a circuit board installed in the accommodating space, a port soldered to the circuit board and corresponsive to a slot of the base, and a thermosetting gel covered onto the port and the soldered portion of the circuit board and the port. The base has a corresponding cover made of a thermosetting gel by injection, so that the cover is packaged into the base, and the circuit board and the port are packaged in the base and the cover, and an interface of the port will not produce any gap. Therefore, moisture or dust will not enter from the interface to achieve the waterproof and dustproof effects.

Abstract: A switch is equipped with an indicating lamp assembly, which is secured in a control of the switch, and which includes a first lamp, and a second lamp respectively used for helping people find the switch in the dark, and for indicating that the switch has been switched on; the first and the second lamps have a common leg, and a respective second leg; the common leg is electrically connected with a terminal of the switch; the second leg of the first lamp touches another terminal of the switch; the second leg of the second lamp will touch yet another terminal of the switch as soon as the switch is switched on therefore the second lamp will begin to produce light as soon as the switch is switched on for allowing power to be supplied through it.

Abstract: A switch includes a transparent housing, a control member, and several light emitting elements; the control member is held in and pivoted to the housing with a depressed portion being within an opening at one end of the housing; the housing has two side compartments on two sides of a middle compartment, and an annular protrusion around the opening on an outer side thereof; the light emitting elements are held in the side compartments of the housing with legs thereof projecting outwards through other end of the housing such that the switch is available with the light emitting elements therein, and such that a circle of light will show on the annular protrusion around the control member when the light emitting elements are powered.

Abstract: A timed switch has a housing member, an output connecting leg connected to an appliance, and a circuit board including both a timing device and an electromagnet. The output connecting leg is electrically connected to the circuit board, and has a front end movable member disposed behind the front wall of the housing member. A control button is pivoted to the outer side of the front wall from a middle with an upper and a lower pushing protrusions passing through the front wall to abut an upper part and a lower part of the movable member respectively. A first, and a second input connecting legs are provided, which are connected to the power, and the second further to the circuit board.

Abstract: A switch has a base and a depressable member up-and-down movably received in the base. The base has conductive rods passed through the bottom; each having a first contact facing a respective one of second contacts of a bottom of the depressable member and a lower part sticking out for connection with a socket. A fixing hook has a lower portion held in position on an elongated slot of the base bottom, a leaning portion connected to one end of the lower portion, and an engaging portion connected to the upper end of the leaning portion. The depressable member further has an engaging surface facing the engaging portion for disengagably engaging the hook engaging portion. The depressable member is normally biased up to a power-off position by a spring positioned on the lower position of the hook.
