Provided is an electric switch, including a casing, an actuator, a movable contact frame, a snap-action resilient member, a lock mechanism, a signal switch and a contact switch. The actuator is capable of reciprocating along a first direction. The movable contact frame is provided with a retaining portion. The snap-action resilient member is arranged in the movable contact frame and is compressed by the actuator when the actuator moves. The lock mechanism includes two lock members which are capable of reciprocating in the mounting cavity along a second direction with the movement of the actuator, so as to lock or unlock the retaining portion. A brush of the electric switch is arranged on the movable contact frame. A movable contact of the contact switch is arranged on the movable contact frame.

A control element having a beam member divided into an actuation section and a valve section positioned on opposing sides of a pivot member, in which active control of the actuation section causes buckling of the valve section to bring the valve section from a closed state to an open state or causes relaxing of the valve section to bring the valve section from an open state to a closed state.

A valve assembly that provides reliable opening and closing valves at specified times despite changing performance characteristics of the valve is disclosed. The valve assembly includes a controllable valve selectively actuatable to control flow of a fluid therethrough, with the controllable valve having a variable valve open/close response time. The valve assembly also includes a plurality of sensors configured to measure current operational parameters of the controllable valve and/or the fluid and a valve controller programmed to process valve timing control instructions generated by an external source, process inputs from the plurality of sensors regarding the measured operational parameters of the controllable valve and/or the fluid, and provide an actuation signal to the controllable valve based on the valve timing control instructions and the inputs from the plurality of sensors, so as to control a timing of an actuation of the controllable valve.

A breaker mechanism for an electrical circuit breaker is disclosed, the breaker mechanism including a spring, a latching mechanism and an actuating element, with which a breaker shaft of the electrical circuit breaker is actuated for breaking (OFF position) or making (ON position) the electric current. In an embodiment, the actuating element is actuated in the direction of the ON position when making the electric current, and the spring is thereby tensioned. Further, the latching mechanism releases the energy of the spring for actuating the breaker shaft of the electrical circuit breaker when the ON position is reached.

A keypad includes a base, an actuator, a first and second elastic member and a pivotal mechanism. The base has a through hole. The actuator is located in through hole to be moved between initial position and pressed position. The first elastic member is connected between the base and the actuator. The pivotal mechanism is pivotably and linearly movably disposed on the actuator to be moved between withdrawn position and protruding position. The second elastic member is connected between the actuator and the pivotal mechanism. The base has stop block and recess and the pivotal mechanism has tooth. While the actuator is moved to the pressed position, the tooth is stopped by the stop block so that the pivotal mechanism is pivoted and then linearly moved to the withdrawn position, and then enters into the recess, enabling the pivotal mechanism to the protruding position and press a switch.
