摘要： A stored energy-type circuit breaker includes a sensor that operates as a full open sensor, and that is used to prevent the circuit breaker from closing in response to either a closing signal or a manual operation. The full open sensor exhibits a first output condition when the moveable contact is in a fully open position and a second output condition when the moveable contact begins to leave the fully open position. An electronic trip unit (ETU) is electrically connected to the sensor and, when in a close break mode, blocks the circuit breaker from closing. The ETU does this by, upon detecting that the sensor is in the second output condition, generating a signal that will cause the breaker's opening spring to return the moveable contact to the fully open position.

摘要： A power transfer switch suitable as a bypass switch connecting a utility feed to a load comprises a bi-stable actuator selectively driven by a compression means charged by a handle. A latch retains the actuator until suitable power source conditions are detected to allow the transfer to proceed. The controller releases the latch and the actuator abuts breakers in sequence to effect a reliable make-before-break or break-before-make transfer.

摘要： A latching device for an operating mechanism for an electrical switching apparatus. The device has a locking member movable between a first position and a second position. In the first position the locking member is arranged to lock a drive member of the operating mechanism in a locked position, and a force of the drive member being applied to a contact portion of the locking member. In the second position the locking member is arranged to release the drive member from the locked position. At least in the first position the locking member is arranged to bear against the counter roller. A tripping member is movable between a first position locking the locking member and a second position releasing the locking member. The locking member has a first portion and a second portion. The first portion is rotatable connected to a first link around a first pivot axis, which first pivot axis is movable perpendicular to its direction. The second portion is rotatable connected to a second link around a second pivot axis and movable perpendicular to its direction. The second link is rotatable connected to the tripping element around a third pivot axis. Movement of the tripping member from its first position to its second position initiates movement of the contact portion out of force-transmitting relation with the drive member.

摘要： A trigger assembly for an electrical device that includes a main body having a housing within which an electrical switch unit is disposed. The trigger assembly may include a trigger member having an engagement portion that is hingedly connected to the main body so that the trigger member is rotatable about a hinge relative to the main body. The trigger assembly may include an actuator member operably-connected to the trigger member that is movable between an OFF position and an ON position. The trigger assembly may include a lock-off mechanism including a lock-off member that is selectively operable to restrict movement of the trigger member towards the main body and to thereby restrict movement of the actuator member from the OFF position into the ON position, and, to not restrict movement of the trigger member toward the main body.

摘要： A power tool (1) includes an electric motor (2) as a drive source and a start switch (20; 61) that starts the electric motor (2) and is lockable in an ON position in a lock-ON state. An electromagnetic actuator (30; 40; 50; 60) pushes out or pulls in an actuation pin (30a; 40a; 50a; 60a) with respect to a body of the electromagnetic actuator (30; 40; 50; 60) in response to cutting off of a supply of electrical current to the power tool (1). The pushed-out or pulled-in actuation pin, directly or indirectly, disengages the start switch (20; 61) from the lock-ON state and/or prevents the start switch (20; 61) from being shifted into the lock-ON state.

摘要： The present disclosure provides an input device that puts signals into equipment in response to turning action and that can come down in thickness along an axis of a rotary shaft. The input device includes a knob configured to be turned, a rotary shaft configured to turn together with the knob, and a flange disposed around an outer peripheral surface of the rotary shaft. The flange is designed to regulate turning of the rotary shaft. The input device further includes an elastic component that is disposed around the outer peripheral surface of the rotary shaft and is fastened to the flange, a rotation controller that permits or inhibits turning of the elastic component, and a detector that detects a rotational state of the rotary shaft.
