The invention relates to an electrical switch device comprising contacts which are mobile through actuation of a first rotation shaft (10) and a control mechanism (1) for the mobile contacts which is situated in a housing and which can be rearmed via a second rotation shaft (20). The first rotation shaft (10) passes through a first wall (2, 3) of the housing and the device comprises a first rotation sensor (12) coupled with the first rotation shaft (10) outside of the housing, so as to measure the angular displacement of the first rotation shaft. The second rotation shaft (20) passes through a second wall (2, 3) of the housing and the device comprises a rearming module (25, 26) removably fixed outside of the housing against the second wall (2, 3), so as to be coupled with the second rotation shaft (20) to be able to rearm the control mechanism.

A switch, in particular a low-voltage circuit breaker, in plug-in technology includes a withdrawal shaft to move the switch from an operating position into a removal position; a force store including a storage spring unloaded during withdrawal; and an unlatching shaft which, as the circuit breaker is withdrawn, is configured to rotate into an unlatching position, unloading of the storage spring taking place when the unlatching shaft is in the unlatching position. To permit unloading of the force store during the withdrawal, the unlatching shaft includes a driver element, spaced radially apart from its axis of rotation and configured to rest in a sliding manner on an outer contour of a rotatably mounted cam disk. The withdrawal shaft and the cam disk are connected via a connecting element which transforms the rotation of the withdrawal shaft into a corresponding rotation of the cam disk and therefore, of the unlatching shaft.

A switch, in particular a grounding switch, is for quickly establishing a ground connection and for extinguishing an arc fault for a switching system. The grounding switch includes at least one fixed contact having a first cable feed, a moving contact, a contact guide having a second cable feed, and a mechanical energy store. In the opened state, an insulating distance between the fixed contact and the moving contact, is filled with insulation liquid, at least in part. The switch further includes a triggering device and a locking mechanism.

A stored energy assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing and a mount coupled to the housing. The stored energy assembly includes: a ratchet assembly having: a first ratchet member, a second ratchet member, and a shaft extending through the first ratchet member and the second ratchet member, the shaft being structured to extend through the mount; a stored energy mechanism coupled to the shaft; at least one charging mechanism structured to charge the stored energy mechanism in order to store energy; and a clutch assembly including a link assembly cooperating with the first ratchet member and the second ratchet member in order to transmit energy from the charging mechanism to the stored energy mechanism.

The present application relates to a clutch mechanism for an energy storage device including a load gear, a drive gear, a one-way bearing, a bushing, and a gear shaft including a gear portion and a clutch portion. The gear shaft includes multiple cylinders, and a push rod, a rotary sleeve and an elastic element located in a cavity of the gear shaft. The push rod includes a push rod slide hole and a push rod connecting hole, for connecting to the gear shaft and the rotary sleeve, respectively. A press block is fixed to the drive gear, the press block being capable of pushing the push rod to slide axially, so as to unlock or lock the bushing and the gear shaft. A gas insulated circuit breaker using such a clutch mechanism is also disclosed.

An opening switch and a remote circuit breaker are provided. The opening switch includes a base, and an energy storage assembly and a lock catch assembly that are disposed on the base; the energy storage assembly is disposed on an inner wall of the base, one end of the lock catch assembly is hinged to the base, a lock catch protrusion is disposed on the lock catch assembly, and the lock catch protrusion includes a barrier wall; and when the barrier wall is configured to abut against an energy storage arm of the energy storage assembly, under an action force of the energy storage arm, the lock catch assembly has a rotation tendency, so that the energy storage assembly maintains an energy storage state.
