A circuit breaker includes a vacuum interrupter having a closed position and an open position. The circuit breaker includes a linkage operatively coupled to and extending from the vacuum interrupter and a high-speed actuator operatively connected to the linkage. The high-speed actuator is operable to move the linkage by a repulsion force and cause the vacuum interrupter to move to the open position. The circuit breaker includes a decelerator with an integrated latch assembly operatively coupled to the high-speed actuator. The decelerator decelerates the repulsion force of the high-speed actuator and latches the actuator with the integrated latch assembly to maintain the vacuum interrupter in the open position.

The present invention discloses a muted key module, an electronic device and an implementation method. The key module includes a switch member, a triggering mechanism and a supporting member, wherein the triggering mechanism is arranged corresponding to the switch member. The triggering mechanism can be moved along the contacting and separating directions of the switch member, thus to realize an ON or OFF operation of the switch member. A muting layer is arranged between the switch member and the supporting member. In the present invention, the muting layer is arranged between the switch member and the supporting member, so the impact force the between the triggering mechanism and the switch member can be cushioned by the muting layer, thereby reducing the noise produced when the key is pressed, thus to improve the quality of the final product as a whole.

An assembly and a method for damping contact bounce in high-voltage circuit breakers include a vacuum interrupter and a holder for the vacuum interrupter. The vacuum interrupter includes a housing, at least one movable contact piece and at least one fixed contact piece. At least one mass body is mechanically connected to the at least one fixed contact piece in order to effect damping of the contact bounce between the at least one fixed contact piece and the at least one movable contact piece during a switch-on operation of the high-voltage circuit breaker.

A control device capable of providing rotational damping through an elastic force is provided directly at the base of an electronic product and includes an adjusting member and an elastic member. The adjusting member is rotatably provided at the base. The adjusting member has a bottom portion corresponding to a switch provided in the base. The adjusting member further has a head portion outside the base. The elastic member is provided between the adjusting member and the base. The elastic force of the elastic member acts between the head portion of the adjusting member and the base to change the rotational damping to which the adjusting member is subjected.

A force-controlled-switch comprises a diaphragm spring element and an absorber-plate. The absorber-plate is configured to absorb kinetic energy of the force-controlled-switch. In particular, the absorber-plate absorbs a part of the diaphragm-spring-element's kinetic energy.

An assembly for damping switching movements has a housing, which physically surrounds at least one piston, and which at least partly physically surrounds at least one rod. The rod is movable relative to the housing. The piston delimits a first fluid volume, which is fluidically connected to a second fluid volume by way of a throughflow opening. The rod is formed at one end as a hollow tube and physically surrounds the first fluid volume. The piston is guided in the hollow-tubular end of the at least one rod. A method for damping switching movements in a high-voltage circuit breaker includes decreasing a damping rate of the assembly for damping in a period in the time profile of the switching movement, in particular after a previous increase in the damping rate during the switching movement.

An electromagnetic relay includes a mobile component movable at time of energization and de-energization of a coil, and a fixed component immovable at the time of energization and de-energization of the coil. A damping space is provided between the mobile component and the fixed component and changes in volume with the movement of the mobile component. A gap provided between the mobile component and the fixed component serves as a passage that allows gas to flow into or out of the damping space when the damping space changes in volume. A size of the gap is set such that a pressure is generated in the damping space to cause a damping force acting on the mobile component when the damping space changes in volume.
