A universal serial bus (USB) interface is used to connect to a USB device. When the driving pole of the USB interface is pressed, the conductive washer of the USB interface is driven to move away from the first terminal and the second terminal of the positive differential signal pin of the USB interface, an electrical connection between the first and second terminals of the positive differential signal pin is cut. When the driving pole is loosed, the conductive washer returns back, to contact the first terminal and the second terminal of the positive differential signal pin, the first and second terminals of the positive differential signal pin are thus electrically connected.

An architectural preset rotary and preset slide control device comprising an N-mode latch mechanically coupled to a switch having a pole and a plurality of receiving terminals. The device further comprises a variable control component that is electrically coupled to the switch such that when the latch is activated into one of the N modes, the switch pole is caused to be electrically coupled to one of the receiving terminals allowing electrical energy at the pole to be routed through the switch to one of the receiving terminals. The variable control component controls the amount of electrical energy that is routed through the switch. The device has a modular design in that the switch, latch, variable control component and other parts of the device are single piece parts that facilitate the assembly of the device during its manufacture.

An extension control apparatus for a wall switch mounted within a wall. The wall switch has a moveable lever extending through the cover plate. The apparatus consists of a housing secured to the cover plate, an elongated vertical rod connected to a cap placed over end of the lever extending through the housing and a pair of stoppers affixed to the rod on either side of a guide member mounted to the wall to limit travel of the rod when the rod is manually operated up and down to activate the lever of the wall switch.

A lighting apparatus includes a light source, a driver, a light housing, an actuator unit, a light passing cover, and an external switch. The driver is used for converting an external power to a driving current supplied to the light source. The light housing is used for disposing the light source and the driver. The actuator unit is connected the driver for configuring a working status of the driver. The light passing cover is fixed to the light housing for a light of the light source to pass through. The external switch is mechanically connected to the actuator via a through hole of the light passing cover for the actuator to generate a control message to the driver. The driver controls the light source according to the control message to configure the working status of the light source.
摘要:
This is directed to a bend switch constructed from two substantially co-linear elongated bodies having opposing contact surfaces. In an open switch position, the contact surfaces remain apart, preventing electrical coupling. To close the switch, a user can bend the elongated bodies relative to each other to cause the contact surfaces to meet, thus creating an electrical coupling. Each elongated body can have several independent conductive portions. The bend switch can include a movable space member placed between the elongated bodies to maintain the contact surfaces a predetermined distance apart in the open switch position. The movable space member can include preferred or non-preferred bending orientations, equilibrium positions, and/or a potentiometer for closing the switch. The bend switch can control one or more functions (e.g., microphone, volume, or playback controls) of an electronic device (e.g., portable media device or cellular telephone) coupled to the bend switch.

A non-fused electrical slide switch. A handle assembly is operatively connected to a base, between on and off positions, and movable relative to a cover. The base has two pair of raised landings rising above four contact strips. Each pair of raised landings are disposed between one load and one line contact strip of the four contact strips and between the one load contact strip and partitions of the base, respectively. A shoe assembly includes a pair of contact shoes and at least one pair of springs biasing the pair of contact shoes. Depending portions of each contact shoe are in direct contact with associated load and line contact strips allowing electrical communication therebetween. The two pair of raised landings prevent arcing as the handle assembly traverses the on/off positions by raising the depending portions of each contact shoe immediately after they leave contact with the associated load and line contact strips.

A switch assembly includes a housing having a longitudinal axis and a transverse axis. The housing has a pair of spaced apart longitudinally extending walls each having a control curve. An actuating element is mounted to the housing. The actuating element is longitudinally movable along the longitudinal axis between two switching positions and is pivotable about the transverse axis between two other switching positions. A first switching piece is coupled to the actuating element to pivot as the actuating element pivots. A first pair of movable electrical switching contacts is associated with the first switching piece. The first switching piece moves one of the first pair of switching contacts as the actuating element pivots. A second switching piece is coupled to the actuating element to pivot as the actuating element longitudinally moves. A second pair of movable electrical contacts is associated with the second switching piece. The second switching piece moves one of the second pair of switching contacts as the actuating element longitudinally moves. A control device extends transversely across the housing. The control device has two spring loaded pressure pieces which each engage one of the control curves of the two walls to be biased to move the actuating element from a switching position to return to an initial position.
