Abstract:
An electrical panel assembly comprising at least one circuit breaker and a mounted low-profile circuit breaker lock-out assembly is disclosed. The circuit breaker lock-out assembly includes a first and second mount. The first mount is for mounting to a first end of a circuit breaker housing wall adjacent a circuit breaker switch lever and includes an outward projection having a through-hole. The second mount is for mounting to a second end of the circuit breaker housing wall and includes a pivotally attached arm that is rotatable between an unlocked and locked position in which the arm is aligned with the outward projection allowing a lock to be inserted through the projection through-hole and a corresponding hole in the arm. The arm is shaped to receive the circuit breaker switch lever and hold the lever immobile when the arm is in the locked position and the lock is inserted.
Abstract:
The invention is a retrofit device for converting a standard switch to a smart switch. The retrofit device taps into an existing switch electrical terminal via one or more sliding arms with electrical contacts. The electrical contacts interface with the terminals, thus providing a control circuit to intervene or interrupt the existing switch function and allow a control system to control the electrical circuit the existing switch serves.
Abstract:
A power-circuit breaking device includes a receptacle and a plug. The receptacle includes a power terminal and a signal terminal. The plug includes a main terminal and a sub-terminal. The plug includes a plug housing, a lever which is attached to the plug housing, a lock slider which is attached to the plug housing, and a sub-connector which is supported by the lock slider. The plug housing holds the main terminal. The sub-connector holds the sub-terminal. When the lock slider slides, the sub-connector moves. When the lever is located at a closed position, the main terminal is connected to the power terminal. When the lock slider is located at a connected position, the sub-terminal is connected to the signal terminal.

The module includes a module housing including a bottom surface, side walls, and an open face, a printed circuit board (PCB) received from the open face of the module housing and securely disposed within the module housing at a distance from the bottom surface of the module housing; power switches mounted on a top surface of the PCB, and heat sinks discretely arranged and each mounted over a respective one of the plurality of power switches and secured to the top surface of the PCB to transfer heat away from the power switch through the open face of the module housing. The module further includes an input unit having conductive tracks disposed on the PCB and an electro-mechanical element engaging the plurality of conductive tracks, the input unit generating a signal for controlling a switching operation of the plurality of power switches, and a controller mounted on the PCB configured to control the switching operation of the power switches based on the signal from the input unit.
Abstract:
A power tool is provided including a tool housing, an electric motor disposed in the housing, and a variable-speed actuator having a trigger, a sliding member linked to the trigger and moveable in a longitudinal direction, and a compression spring engaging the sliding member and a wall arranged at a distance from the sliding member in the longitudinal direction. A post is disposed on the wall, where an end of the compression spring engaging the wall is disposed around the post to limit a lateral movement of the compression spring.
Abstract:
A switch for controlling wiper delay includes a housing, a circuit board having a contact pattern of several parts on a surface thereof positioned in the housing, some of the contact pattern parts being arranged in a closely-spaced, radially-extending array, a carriage rotatable in the housing, electrical contacts mounted on the carriage and disposed for engagement with selected parts of the contact pattern as a function of the position of the carriage, a discrete resistive element having at least three conductive leads extending therefrom and subdividing the resistive element into a resistor network having a plurality of resistive values, each conductive lead of the resistive element being conductively affixed to a respective one of the contact pattern parts in the array, and wherein the carriage is manually actuatable to place the electrical contact into contact with successive ones of the contact pattern parts in the array to vary the interval between sweeps of a wiper. An additional electrical contact resiliently supported by a conductive beam spring has one end mounted in fixed conductive engagement with one of the contact pattern parts of the circuit board. The beam spring is biased into engagement with a cam surface on the periphery of the carriage for selective electrical connection of that additional contact with another of the circuit contact pattern parts as a function of carriage position to control high speed operation of a wiper motor.
Abstract:
This invention is an improved electrical switch in which the housing is molded in one piece with the terminals being thereafter slidably inserted into an arcuate in cross section slot with a cover plate permanently retaining the same. This switch is so designed that even miniature configurations are capable of handling current loads without danger of internal arcing.
Abstract:
A rotary switch of sliding contact type for use in a torque converter of an automotive vehicle comprises a base in the surface of which a plurality of stationary contact plates are molded, a cover plate for the base plate suitably secured to the latter with a space for movably enclosing a rotary contact arm between the cover plate and the base plate, and a rotatable shaft fixedly received in the hub of the rotary contact arm. The hub is rotatably held between edges of corresponding openings formed in the base plate and the cover plate, so that, upon rotation of the shaft, contacts of the rotary contact arm slide across the stationary contact plates and can be stopped at positions precisely corresponding to predetermined angles of rotation of the shaft.
Abstract:
A switch structure used for switching on or off an electronic system is provided. The switch structure includes a base, a switch body pivoted to the base, a first electrode connected and moved along with the switch body, a second electrode disposed on the based and corresponds to the first electrode, a torsion assembly, and a power source. The first electrode and the second electrode are electrically connected to the electronic system, respectively. The torsion assembly is connected to and drives the switch body, so as to drive the first electrode and the second electrode to switch between a conductive state and a non-conductive state. The power source is connected to the torsion assembly, and the power source provides a torsion to the switch body via the torsion assembly in an automatic state so as to switch the switch structure between the conductive state and the non-conductive state.
Abstract:
A panel-type control button, including: a press key base, a press key panel, a switch board and a springback soft key. The press key panel is snap-fitted on top of the press key base, and one end of the press key panel is rotatably mounted at one end of the press key base. The switch board is located below the press key base, and is provided thereon with a switch mechanism. The springback soft key is located above the switch mechanism of the switch board. When the press key panel is pressed, the press key panel comes into contact with the springback soft key and triggers the switch mechanism on the switch board, and further controls the opening and closing of the switch mechanism. The springback soft key provides a springback force for the press key panel to reset.
