Abstract: An electric connector switch for connecting lighting fixtures to a power cable is disclosed to include an electrically insulative housing, a connector body mounted inside the housing to hold a grounding unit and a conducting unit, and a switching member for controlling on/off status between the conducting unit and the power cable. The conducting unit has two fixed electrodes respectively connected to the positive and negative poles of the power cable, and a movable electrode, which has one end constantly kept in contact with one fixed electrode and the other end movable by the switching member between the on position to contact the other fixed electrode and the off position to be disconnected from the other fixed electrode.

Abstract: A track lighting fixture comprising a power connector, an adjustable holder shell assembly connected to the power connector to hold a lamp. The adjustable holder shell includes an outer shade, a hollow rotating member, a rotary cap capped on the rotating member and coupled to the rear side of the outer shade for rotating the rotating member, and a sliding member mounted in the hollow rotating member and holding the lamp on the inside and a first guide rod extending inserted into an axial guide groove in the outer shade and a second guide rod inserted through a front notch of the hollow rotating member and movable along a spiral groove around the periphery of the hollow rotating member for causing axial movement of the sliding member and the lamp relative to the outer shade upon rotation of the rotating member by the rotary cap.

Abstract: A socket switch for a light bulb comprises a shell, a main body, a grounding unit, a switch unit, an electric conduction unit, wherein a holding chamber is formed inside the shell. The shell has two coupling holes formed thereon. The grounding unit, the switch unit, and the electric conduction unit are connected a surface of the main body, and this surface of the main body is screwed onto the shell via the coupling holes and located inside the holding chamber. The switch unit is designed for electrically connecting an electrode of a power supply, which is connected to the electric conduction unit, with an electrode of the light bulb for lighting up this light bulb. As a result, the purpose of saving energy can be achieved by controlling electric conduction between the power supply and the light bulb.

Abstract: A track and connector arrangement for a track light in which the connecting unit at each end of the connector has two conductor holders holding positive and negative conductors at a respective metallic spring plate, and the track has two electrically conductive wire rods of rectangular cross-section that are respectively inserted into the conductor holders and held in contact with the respective metallic spring plate in each conductor holder to receive power supply from the positive and negative conductors after connection of the connector to the track.

Abstract: A track and connector arrangement in which the track (1) includes a metal casing (1), an insulator strip (12) mounted inside the casing (1) and having two opposed inside flanges (123), and two metal conducting strips (13) bilaterally mounted within the insulator strip (12) between the inside flanges (123) and flat top wall (121) of the insulator strip (12); the connector (2) includes a shell (21) longitudinally abutted against one end of the metal casing (11) of the track (1), a terminal holder (22) securely mounted on the shell (21), the terminal holder (22) having a protruding portion (2213) plugged into a positioning space (14) between bottom walls (113) of the metal casing (11) and inside flanges (123) of the insulator body (12), and two electric terminals (222) longitudinally bilaterally mounted on the terminal holder (22), the electric terminals (222) each having a curved springy contact portion (2222) at one end respectively pressed on the metal conducting strips (13) in the insulator strip (12) inside

Abstract: An adapter and track arrangement in which the track includes a metal casing, an insulator strip mounted inside the casing and having two opposed inside flanges, and two metal conducting strips bilaterally mounted within the insulator strip between the inside flanges and flat top wall of the insulator strip; the adapter includes a first shell, a second shell covered on the first shell to hold electric wires and electric contacts at the ends of the electric wires, a third shell covered on the second shell, and a latch mounted in the third shell and operated to lock the adapter, the latch having two spring arms, which are deformed when the latch is forced down to unlock the adapter, or automatically return to their former shape to force the latch into the locking position to lock the adapter when the latch is released from the user's hand.
