摘要:
A circuit interrupter having a moveable contact arm that forms part of the linkage assembly that connects to the handle. The moveable contact arm positioned essentially vertically in the circuit interrupter housing and positioned such that any arc that develops is drawn in a direction away from the moveable contact arm. The moveable contact arm moveable about two pivot points when the contacts are opening and closing, one of the two pivots positioned in a curved channel to slidingly move in the channel during opening and closing.

A circuit interrupter 100 configured to aid in rapidly extinguishing an electrical arc regardless of the polarity of current through a circuit interrupter, and during low current conditions. Various implementations of the circuit interrupter incorporate an electromagnet 705 and a pivoting permanent magnet 192, 705. These structures produce additive magnetic fields that create a force on an arc 190 between the contacts 120, 140, urging it toward an arc arresting structure 191 regardless of the electrical polarity of the circuit interrupter or the magnitude of the current through the circuit interrupter.

A rotary switch having a body, a rotary knob attached to the body, and at least two terminals attached to the body. An actuator is pivotably mounted within the body and operably connected to the rotary knob, the actuator pivoting upon a rotation of the rotary knob. A conductor is pivotably mounted in the body and is in communication with the actuator. The conductor is adapted to connect or disconnect the at least two terminals when the actuator is pivotably moved.

A rocker switch having a housing and a rocker extending from the housing. The rocker has a first side with a first end and a second end, a second side adjacent to the first side, and a channel. The channel is disposed on the second side of the rocker and has a first end and a second end. A pivot point is disposed on a crank. A pin, disposed on the crank, is located in a first side of the channel. The depression of the first end of the rocker causes a rotational movement of the channel in a curvilinear path around the pivot point, causing a rotational movement of the crank, moving the pin from the first end of the channel toward the second end of the channel.
摘要:
A circuit breaker having a movable contact arm (120, 675) for opening and closing the circuit which is controlled separately by a circuit breaker mechanism for circuit protection (140) and by a switch lever (160, 660) mechanism which does not require actuation of the circuit breaker mechanism to function. The switch lever (160, 660) may also be activated remotely by a remote actuator (180, 680), for example, a solenoid. A manual reset mechanism is provided so that, actuation of which, when power has been lost to the remote actuator (180, 680) when the remote actuator (180, 680) is in the off position, moves the remote actuator (180, 680) to the on position, thereby resetting the circuit to the closed state.

A control system for electrical devices in a vehicle has solid state output/relay (12) modules with processing and memory capability. The output/relay module (12) is programmable to store configuration data corresponding to predetermined states for the various devices to be controlled. The output/relay (12) module has memory capability including a non-volatile component (EEROM, 47). A solid state input module also has processing capability, and includes memory capability. The input module has selector switches for preselecting a variety of device states. The input module further provides a visual indication of the states for these devices. A data bus (203) provides communication between said input and output modules, and a dongle (201) is selectively connected to said relay module data bus (203) for allowing changes to the configuration data (217) stored therein. The dongale (201) is programmable from a personal computer or work station.

A rocker switch assembly includes a housing having at least one bracket with a bracket stop formed therein, and a rocker actuator pivotably mounted on the housing. At least one wedge lock is pivotably mounted on the rocker actuator, the wedge lock pivotable between a locked position in which the wedge lock engages the bracket stop formed in the bracket, thereby preventing pivoting of the rocker actuator with respect to the housing in at least one direction, and a retracted position in which the wedge lock is disengaged from the bracket stop formed in the bracket so as to allow for pivoting of the rocker actuator with respect to the housing. A lock release button is also provided, actuation of which from a resting position to a release position causes the wedge lock to move to the retracted position.
摘要:
A circuit breaker design allows for the circuit breaker to have an overall width (i.e., measured along the circuit breaker's exposed outwardly-facing surface of its housing) that is narrower than achievable with known typical configurations, while at the same time still providing robust arc interruption capabilities. This is achieved in large part by providing a specific orientation of a moveable contact arm assembly and/or by providing a specific configuration of a current path within the housing.
