A power switch including a line input configured to receive a line voltage, a load output configured to output the line voltage, a contact, a switch, a housing including a rear portion and a front cover coupled to the rear portion, an indicator supported by the front cover, the indicator configured to provide an indication of the power switch, and an indicator lens positioned between the indicator and the front cover. The contact is configured to selectively electrically connect the line input to the load output, the contact having a closed position in which the line input is electrically connected to the load output, and an open position in which the line input is not electrically connected to the load output. The switch is configured to selectively control the contract between the open position and the closed position.

A control device for a movable contact relative to a fixed contact of a vacuum bottle of an electrical switching device. The control device includes a principal mechanism for disconnection and connection of the contacts, of the mechanical energy accumulation type. The control device further includes an auxiliary disconnection-assistance mechanism arranged such as to accumulate mechanical energy when the movable contact is moved towards the connection position and such as to restore the mechanical energy thus accumulated in such a manner as to exert an additional disconnection force in the form of an impact tending to move the movable contact from the connection position towards the disconnection position when the movable contact is immobilized in the connection position despite the action of the principal disconnection force.

Electrical switching device, including separable electrical contacts, a switching mechanism and a control lever. This switching mechanism is designed to move the separable contacts reversibly and selectively between a stable closed state and a stable open state. The control lever can be moved between a closing position and an opening position. The switching mechanism is configured to move the separable contacts from their closed state to their open state when the lever is moved from its closing position to its opening position, and to this end includes a spring which, between the closing position of the lever and a first intermediate position referred to as the “dead point”, exerts a force that opposes the movement of the lever and which, between the dead-point position and the opening position of the lever, exerts a force that drives the contacts towards the open position. The switching mechanism comprises a holding device which is configured to prevent the switching mechanism from moving the contacts towards their open position when the lever is moved from the closing position to the opening position and when the lever has not passed a second intermediate position located between the dead-point position and the opening position.

An operating attachment for arrangement on a predefinable switching device and for operating a pivotable switching device toggle of the switching device includes: a one-sided open housing positionable on the switching device; a rotatable shaft having a rotation axis; a manual operating part, the manual operating part being situated on the rotatable shaft; a switch-on projection for pivoting the switching device toggle in a first pivot direction, the switch-on projection being situated on the rotatable shaft; a switch-off projection for pivoting the switching device toggle in a second pivot direction opposite the first pivot direction, the switch-off projection being situated on the rotatable shaft; and a housing stop for contacting a stop edge of the switch-off projection, the housing stop being situated in the one-sided open housing. The switch-off projection yields resiliently such that the switch-off projection is bent for contact with the housing stop.

A control device for a movable contact relative to a fixed contact of a vacuum bottle of an electrical switching device. The control device comprises a principal mechanism for disconnection and connection of the contacts, of the mechanical energy accumulation type. The control device further comprises an auxiliary disconnection-assistance mechanism arranged such as to accumulate mechanical energy when the movable contact is moved towards the connection position and such as to restore the mechanical energy thus accumulated in such a manner as to exert an additional disconnection force in the form of an impact tending to move the movable contact from the connection position towards the disconnection position when the movable contact is immobilized in the connection position despite the action of the principal disconnection force. The additional disconnection force may, in particular, be transmitted by a strike arm entrained in rotation through the action of an auxiliary disconnection spring until one of the ends thereof strikes a lever of the principal mechanism or a component connected to the lever.

A power switch including a line input configured to receive a line voltage, a load output configured to output the line voltage, a contact, a switch, a housing including a rear portion and a front cover coupled to the rear portion, an indicator supported by the front cover, the indicator configured to provide an indication of the power switch, and an indicator lens positioned between the indicator and the front cover. The contact is configured to selectively electrically connect the line input to the load output, the contact having a closed position in which the line input is electrically connected to the load output, and an open position in which the line input is not electrically connected to the load output. The switch is configured to selectively control the contract between the open position and the closed position.

A power switch including a contact configured to selectively electrically connect a line input to a load output, a switch configured to selectively control the contract, and an indicator. The contact has a closed position in which the line input is electrically connected to the load output, and an open position in which the line input is not electrically connected to the load output. The switch has an on position wherein the contact is controlled to be in the closed position, and an off position wherein the contact is controlled to be in the open position. The indicator provides a normal on status, a normal off status, and an error on status.

The present invention relates to a molded-case circuit breaker with a main contact interlock feature preventing improper operation of a tripping mechanism that trips main contacts when the main contacts fuse together. The circuit breaker includes a handle that transfers the user's operational force; a switch lever rotatably mounted on a side plate and connected to the handle, with a pressure portion formed on a part of it; a shaft link, one end of which is rotatably mounted on a shaft pin, that has a contact region on the top; a trip lever rotatably mounted on the side plate, one end of which is slidably connected to the shaft link, and the other end of which is connected to a nail of a tripping mechanism, wherein, if the pressure portion makes contact with the contact region, the trip lever rotates the nail.

A circuit interrupter includes a stationary contact and a moveable contact arm assembly having a moveable contact positioned thereon, the moveable contact configured to be moveable into and out of physical contact with the stationary contact. The circuit interrupter also includes an overcurrent tripping device coupled to the moveable contact arm assembly via a linkage assembly and configured to move the moveable contact out of physical contact with the stationary contact upon detection of an overcurrent situation. The moveable contact arm assembly is connected to the linkage assembly via at least two pivots positioned on the contact arm assembly, so as to cause a relative sliding action between the moveable and stationary contacts as the moveable and stationary contacts are moved into or out of contact with each other such that a wiping action is created in order to clean the moveable and stationary contacts.

The present invention relates to a multi-pole molded case circuit breaker, more particularly, to a multi-pole molded case circuit breaker having a safety device (with an isolation function) which prevents a manipulation handle from being moved to an off-position when a fusion occurs on a contact part.
