The present invention relates to a gripping group for a switch, changeover switch, disconnector or generally a power switch, said power switch being mounted inside an insulated switch body and comprising at least a movable contact providing an electrical connection, said gripping group being configured to grip said at least a movable contact of said power switch, wherein a modular structure comprising a plurality of caliper-like elements being parallelly mounted on a supporting frame and in turn including respective terminal finger elements being angularly movable one with respect to the other, mutually approaching and moving away in contrast with elastic returning means.

The present disclosure discloses a ground fault circuit breaker protector for wrong wiring power-off protection, and belongs to the technical field of ground fault circuit breaker protectors. The ground fault circuit breaker protector includes two conductors fixedly mounted inside a shell. One of the conductors is a power input end; and a line output end is electrically connected to a load output end through a transfer relay and forms the other conductor. The ground fault circuit breaker protector further includes a reset mechanism and a movement arm. By means of pressing the RESET push rod, the push rod is locked on the sliding block by the buckle; under the elastic action of the first springs and the second spring, the sliding block pushes the movement arm to contact the line output end and the load output end.

A push type switch includes a mounting base, a depressing module, a base board including at least a contact portion, a lighting module, a terminal group, and at least a conductive element. The depressing module includes a cap and a connecting peg movably connected to the mounting base. The cap has a light-permeable side portion spaced apart from the mounting base to form an interval. The lighting module includes a flat flexible cable and a plurality of lighting elements located at the interval. When the depressing module is being pushed to depress and deform the at least a conductive element to enable the conductive element to electrically contact the contact portion, the terminal group transmits electrical signals to allow the plurality of lighting elements to light with multiple lighting modes.

A door latch device includes: a first position switch and a second position switch, each including a first contact hole, a second contact hole, and a common contact hole; a common pin configured to be electrically conducted to the common contact hole of the first position switch and the first contact hole of the second position switch by being inserted therein; a first signal pin configured to be electrically conducted to the first contact hole of the first position switch by being inserted therein; and a second signal pin configured to be electrically conducted to the common contact of the second position switch by being inserted therein, wherein the first position switch and the second position switch are configured to perform a switch operation at a same timing of an operation of a predetermined operation detection target.

A centrifugal switch for a motor of a clothes dryer is provided. The end of a bracket and the end of a fixed contact piece are arranged in alignment and each has a raised contact. An upper limit piece slot is provided above the contact of the bracket inside the housing. The aligned ends of the bracket and the fixed contact piece are located above the aligned ends of a starting spring piece, a starting lower piece and a starting upper piece. A pressing head at one end of the rocking lever is located above one side of the fixed contact piece aligned with the bracket. The other end of the rocking lever extends outside the housing. When the centrifuge is not rotating, a movable sleeve of the centrifuge slides into the rocking lever to trigger the centrifugal switch.
