Method for positioning inhibitor switch
An inhibitor switch is attached to a manual shaft with a jig. The jig includes a fitting part and an engagement pin. The fitting part is spline-fitted to an outer periphery of the manual shaft. The engagement pin engages in a positioning hole of the inhibitor switch. The outer periphery of the manual shaft includes a tooth-omitted part formed by omitting at least one of spline teeth. The fitting part includes an insertion hole. The insertion hole includes an inner periphery including internal teeth and an engaging part, wherein the internal teeth meshes with the spline teeth, and wherein the engaging part engages with the tooth-omitted part. The jig is attached to the manual shaft with the engaging part engaged with the tooth-omitted part. The inhibitor switch is rotated about the rotation axis to a position allowing engagement of the positioning hole with the engagement pin.

Electrical contact system
An electrical contact system includes a static contact having a static contact point, a movable contact having a movable contact point, a rotating member on which the movable contact is mounted, and an arc extinguishing device having an arc extinguishing sheet. The movable contact is rotatable with the rotating member between a switch-on position and a switch-off position. When the movable contact is rotated to the switch-on position, the arc extinguishing sheet is rotated beyond a contact area between the movable contact point and the static contact point, allowing electrical contact of the movable contact point with the static contact point. When the movable contact is rotated to the switch-off position, the arc extinguishing sheet is rotated into the contact area between the movable contact point and the static contact point, electrically isolating the movable contact point from the static contact point and cutting off an electric arc.

Switching device
A switching device including a frame, a roll element, a control shaft, a drive system and a roll spring. The control shaft is adapted to control rotation of the roll element such that rotating the control shaft from an ON-position to an OFF-position carries out an opening event in which the roll element transfers from a first position to a second position. The drive system includes an actuator and an actuator spring. The drive system is adapted to rotate the roll element during the opening event to an intermediate position located between the first position and the second position. The roll spring is connected between the frame and the roll element, and is adapted to rotate the roll element to the second position during the opening event.
Switching system, and electrical switching apparatus and switching assembly therefor
A switching assembly is for an electrical switching apparatus of a switching system. The electrical switching apparatus includes a base. The switching system has a communication device. The switching assembly includes a number of contact assemblies coupled to the base, each of the contact assemblies having a stationary contact and a movable contact structured to move between a CLOSED position corresponding to engagement with the stationary contact, and an OPEN position corresponding to disengagement with the stationary contact; and a transfer assembly including an element and only one single actuator coupled to the element, the element being structured to be coupled to the base, the single actuator comprising a controller for receiving a signal from the communication device. The single actuator is structured to move the movable contact of each of the number of contact assemblies between the CLOSED position and the OPEN position.
Effort transmission module
A module for transmission of a force including two toothed wheels which are connected to a main shaft; a first ratchet holder and a second ratchet holder which are provided with a first ratchet and a second ratchet, and are designed such, when they are actuated, to rotate the toothed wheels by support of the ratchet concerned against a tooth of the toothed wheel; a first cam and a second cam, which are designed to actuate respectively the first ratchet according to a first angular course around an axis YY of the first cam, and the second ratchet according to a second angular course around the axis YY of the second cam, which is different from the first angular course.
CHARGING MECHANISM FOR CHARGING A STORED-ENERGY SPRING OF A STORED-ENERGY SPRING MECHANISM
A charging mechanism charges a stored-energy spring of a stored-energy spring mechanism. The charging mechanism contains a charging gear coupled to the stored-energy spring, an intermediate shaft coupled to the charging gear, an idler gear driven by a charging motor, a freewheel coupled to the idler gear, and a dog clutch that couples the freewheel to the intermediate shaft to charge the stored-energy spring and uncouples same from the intermediate shaft in the charged state. The dog clutch contains a first clutch block that is non-rotatably coupled to the intermediate shaft, a second clutch block connected to the freewheel, and a synchronizer ring arranged between the clutch blocks and is non-rotatably coupled to the first clutch block. During a rotation relative to the second clutch block, the synchronizer ring couples in a form-fitting manner to the second clutch block in a first direction of rotation about the axis of rotation.
DEVICE WITH MOVABLE BUTTONS OR SWITCHES AND TACTILE IDENTIFIER
The present teachings provide for a device with a membrane and an underlying switch, an underlying switch actuator, or both that has a unique tactile pattern that is felt through the membrane when the membrane is aligned with the switch, switch actuator, or both, corresponding to the electrical state of the device. The membrane, the switch, the switch actuator or a combination thereof can be repositioned from a first position to a second position so that a different tactile feel is present through the membrane corresponding to a second electrical state.
Dual-power overlapping contact closing mechanism
The present invention discloses a dual-power overlapped closing operation mechanism, relating to the field of dual-power switches. The dual-power overlapped closing operation mechanism comprises a first contact, a second contact, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a seventh connecting rod, a first auxiliary shaft, a second auxiliary shaft and a third auxiliary shaft. The fourth connecting rod rotates anticlockwise to push, via the fifth connecting rod and the seventh connecting rod, the second contact to make electrical contact with the second fixed contact, and at the same time the first contact is first tightly pressed via the second connecting rod and the third connecting rod until the dead point is passed, and then the first contact is gradually opened clockwise. The result of the fourth connecting rod rotating clockwise is similar, in which the second contact is first tightly pressed until the dead point is passed, and then the second contact is gradually opened clockwise. With the present invention, the neutral line overlapping has an extended duration and is maintained by means of a mechanical structure so as to effectively avoid the occurrence of a zero line break.
