Disclosed herein is an industrial cut-off switch for visual identification of power system cut-off status. The industrial cut-off switch includes an enclosure having an accommodation space therein, a handle disposed on an outer surface of the enclosure and having a gripping part extending in one direction, and a switch unit disposed inside the enclosure, and connected to the handle operated to adjust an on/off state of the switch unit.

CIRCUIT BREAKERS WITH HANDLE BEARING PINS
20210358697 · 2021-11-18 ·

Circuit breakers with handles having at least one handle bearing pin that contacts an upper end portion of a moving arm and allows the arm to rotate to “OFF”, “ON” and “TRIP” positions, typically about 90 degrees of rotation.

Slim circuit breaker

A circuit breaker design allows for the circuit breaker to have an overall height (i.e., measured vertically along the circuit breaker's exposed outwardly-facing surface in the typical orientation of circuit breaker panels) that is slimmer than achievable with known typical configurations, while at the same time still providing robust power (e.g., voltage) handling and arc interruption capabilities. This is achieved, for example, by providing various components formed from polymer materials (which are generally less conductive of heat than metals), reinforced by metal members in certain areas, if needed, as well as a very particular configuration of a permanent magnet that is employed for enhanced arc quenching.

In a rocker arm of an electric switch, the electric switch is actuated by the rocker arm for setting definable positions. The rocker arm of an embodiment includes a first part, for setting the definable positions, and a second part, movable between a first position and a second position. In the first position of the second part, the first part can be moved into the definable positions; and in the second position of the second part, the movement of the first part is blocked.

CIRCUIT BREAKER WITH INTEGRATED SAFETY LOCK-OFF MECHANISM
20230368988 · 2023-11-16 · ·

A circuit breaker is configured to ensure electrical safety when working on its circuits. The circuit breaker comprises a housing with an exterior boundary. The housing includes an “integrated” Lock-Off feature. It is integrated to one or more housing components of the circuit breaker not as a separate component to achieve most simplicity and least space used as compared to an “add-on” accessory based Lock-Off feature. The “integrated” Lock-Off feature has a feature that is configured to receive a shackle or a shank of a padlock. The circuit breaker further comprises a built-in Lock-Off mechanism including a handle that is configured to move relative to the feature. The built-in Lock-Off mechanism in combination with the Lock-Off feature is configured to prevent handle from being turned ON with the use of padlock. The padlock prevents circuit breaker from turning ON by impeding the handle from moving to an ON-position.

Contact lever assembly for use with an electrical switch

An electrical switch including a switch housing, a switch circuit disposed within the switch housing. The switch circuit including includes a movable contact member mounted on a contact lever and a stationary contact member. The contact lever is configured for operable-interaction with an actuator. The actuator is configured for movement along an actuator movement axis relative to the contact lever between at least one of an OFF position whereby the contact lever is configured for arrangement in to the first configuration whereby the switch circuit is opened, and, an ON position in which the contact lever is configured for arrangement in to the second configuration whereby the switch circuit is closed.

OPERATING MECHANISM OF CIRCUIT BREAKER, AND CIRCUIT BREAKER
20230377825 · 2023-11-23 ·

An operating mechanism of a circuit breaker, relating to the field of low-voltage electric appliances. The operating mechanism is provided with a double-slider mechanism, a first slider mechanism comprising a first crank, a first connecting rod, a sliding rail and a slider, and a second slider mechanism comprising a contact support, a second connecting rod, a sliding rail and a slider. The double-slider mechanism reduces the space requirement of the operating mechanism while increasing the opening distance of a moving contact, and the breaking performance is good. A circuit breaker comprising the operating mechanism, which provides good breaking performance.

Circuit breakers with handle bearing pins

Circuit breakers with handles having at least one handle bearing pin that contacts an upper end portion of a moving arm and allows the arm to rotate to “OFF”, “ON” and “TRIP” positions, typically about 90 degrees of rotation.

CONTACT LEVER ASSEMBLY FOR USE WITH AN ELECTRICAL SWITCH
20210183604 · 2021-06-17 ·

An electrical switch including: a switch housing; a switch circuit disposed within the switch housing; said switch circuit including a movable contact member mounted on a contact lever and a stationary contact member; the contact lever being configured for operable-interaction with an actuator, said actuator being configured for movement along an actuator movement axis relative to the contact lever between at least one of an OFF position whereby the contact lever is configured for arrangement in to the first configuration whereby the switch circuit is opened, and, an ON position in which the contact lever is configured for arrangement in to the second configuration whereby the switch circuit is closed; a biasing element configured for biasing the contact lever towards the second configuration; so that the switch circuit is closed when the actuator is moved relative to the contact lever in to the ON positions, said biasing element including a first end attached to a first attachment point in connection with a portion of the contact lever and a second end attached to a second attachment point in connection with the switch housing; and an attachment member configured for attachment with the contact lever whereby when attached to the contact lever, said attachment member is configured for operation as the first attachment point in connection with the portion of the contact lever.
