A surgical instrument includes a housing and an elongated shaft operably coupled to an actuating mechanism moveable between an actuated position and an unactuated position. An end effector includes a pair of opposing first and second jaw members. One or more drive surfaces are disposed on the actuating mechanism and configured to compress a spring upon movement of the actuating mechanism to the actuated position. The spring imparts a spring force in a distal direction to bias the actuating mechanism to the unactuated position. An electrically conductive tissue sealing surface extends along a length of one or both of the jaw members and is adapted to connect to a source of electrosurgical energy.

A light-emitting device (1), comprising an LED-module (3) comprising at least one LED mounted on a carrier and at least one connection pad (10a-b) for electrical connection of the LED module (3), a heat dissipator (2) for dissipating heat generated by the LED when in operation, a connection board (4) comprising a substrate having a conductor pattern for enabling provision of external power to the LED module (3), an interconnecting arrangement (7a-d) comprising at least one connection spring (7a-d) attached to the connection board (4) electrically interconnecting the at least one connection pad (10a-b) of the LED module (3) with the conductor pattern of the connection board (4), and an LED-holder comprising at least one holding spring (7a-d) attached to the connection board (4) exerting a spring force there by pressing the LED-module (3) against the heat dissipator (2) to provide a thermal connection between the LED-module (3) and the heat dissipator (2). The interconnecting arrangement (7a-d) is configured to allow movement between the conductor pattern of the connection board (4) and the at least one connection pad (10a-b). The at least one connection spring (7a-d) constitutes the at least one holding spring (7a-d), to simultaneously electrically interconnect the at least one connection pad (10a-b) of the LED-module (3) with the conductor pattern of the connection board (4) and press the LED-module (3) against the heat dissipator (2).

A multi-function leakge protection plug not only can prevent the electric shock accident caused by electrical appliance fault but also can prevent the electric shock accident caused by the power source fault. Therefore, it has earth line live line detecting inductor in the earth line of power source line, zero sequence current mutual inductor, a pair of contact terminal setting between the sub-breaker to each line of phase, zero and earth within the plug, a spring at between the sub-breaker upper end and the copper leaf of earth line active contact terminal to let the spring force attracting to each other always exist on the pair of earth line contact terminal. The safety requirement in electrical operation can be achieved by connecting earth line first and then phase and zero lines or cutting of phase and zero lines first and then earth line when the free releasing device is acting No matter the residual current exists between phase and zero lines or the abnormal cunent exists on the earth line three electrodes in the plug will be cut off simultaneously.
