A photovoltaic Bluetooth headset compartment is provided, comprising: a bottom shell, an upper cover flip-connected with the bottom shell, an inner support assembled on the bottom shell, a photovoltaic panel assembled on an outside of the upper cover, a circuit board assembled in the bottom shell and, a storage battery assembled in the bottom shell and electrically connected to the circuit board, wherein the upper cover is provided with a first spring pin of which one end is electrically connected to the photovoltaic panel and the other end extends from the upper cover, and the inner support is provided with a spring pin contact point electrically connected to the circuit board; and after the upper cover is closed, the first spring pin is inserted into a spring pin contact point and the photovoltaic panel charges the storage battery.

An adapter for use in a track lighting system is designed to be inserted into a track. The track has an electrical conductor means with conductors, the adapter has contact elements, and when the adapter is in an inserted state, contact can be made with the conductors by means of the contact elements. The contact elements can be moved into a contacting position, in which they protrude from the adapter so that they can be connected to the conductors, and into a non-contacting position, in which the adapter can be retracted into or removed from the track. The movement of the contact elements between the contacting position and the non-contacting position can be brought about by an operator by means of a moveably arranged actuating element of the adapter.

A vacuum cleaner of the present invention comprises: a main body having a suction motor for generating suction force; a main PCB capable of generating a control command for the suction motor; a handle part capable of accommodating the main body PCB; and a connector provided at the main body, and to which the main PCB is connected in a process of coupling the handle part to the main body. The main PCB includes a plurality of pads and a slit, and the connector includes: a plurality of connecting pins for making contact with the plurality of pads; and a slit insertion protrusion inserted into the slit.

A dimmable tamper resistant nightlight may include a body comprising at least one light emitting diode (LED). Plug blades may extend from the body. A dimming switch may be coupled to the at last one LED, the dimming switch configured to move between a first position that activates about 50% luminosity of the at least one LED, a second position that deactivates about 100% luminosity of the at least one LED, and a third position that activates about 100% luminosity of the at least one LED. A housing may be coupled to the body, the housing comprising an access opening through which the dimming switch may be moved among the first position, the second position, and the third position. A housing may also comprise a locking element configured to prevent the dimmable tamper resistant nightlight from being removed from the electrical receptacle.
