A water-proof button assembly includes a seat, a sealing member, a button and a contact member. The seat has an opening and an inward protrusion extends inward from the inside of the opening. The sealing member is installed in the opening and has a through hole which is defined by an outer portion. The outer portion contacts the inward protrusion of the seat. The diameter of the outer portion is larger than the diameter of the button. The contact member is located corresponding to the button and contacts the inward protrusion. When the button is pressed, the force pushes the sealing member to contact against the inside of the opening of the seat to enhance the sealing effect between the sealing member and the opening. The sealing member provides a bouncing force for returning the button to the initial position.

A disconnector (1), particularly for photovoltaic applications, comprising at least two modular contact boxes (2), each comprising a box-like body (3) coupled to a contiguous box-like body (3) of a contiguous modular contact box (2). The box-like body (3) form s a central seat (40) that accommodates a rotatable contact (4) and two peripheral seats (50), each of which accommodates a connection portion (51) of a corresponding fixed contact (5) that can be accessed from the outside of the modular contact box (2). The rotatable contact (4) is able to rotate about the axis (40a) of the central seat (40) with respect to the box-like body (3) in order to engage the fixed contacts (5) arranged with their connection portion (51) in the peripheral seats (50) or to disengage from the fixed contacts (5); the two peripheral seats (50) are arranged on the same side (30) with respect to a central plane (A) that passes through the axis (40a) of the central seat (40) and in the fact that the two peripheral seats (50) of a box-like body (3) and the two peripheral seats (50) of the contiguous box-like body (3) are arranged on mutually opposite sides with respect to the central plane (A).

The invention provides a vacuum arc extinguish chamber (100 and 100 '). The vacuum arc extinguish chamber comprises a housing (1), a fixed contact (4) accommodated in the housing (1), a moving contact (5) which is accommodated in the housing (1) and is configured to move so as to be connected with or separated from the fixed contact (4). a conducting seat (12) which is fixedly mounted in the housing (1) and is configured to keep electrical connection with the moving contact (5), and a flexible electric connection structure which is accommodated in the housing (1) and is used for connecting the moving contact (5) with the conducting seat (12); and the moving contact (5) is operated such that the moving contact (5) can be made to move an operation mechanism. The invention also provides a vacuum circuit breaker comprising the above vacuum arc extinguish chamber.

A switching subassembly includes a modular molded interconnect bracket and a switching device arranged on the modular molded interconnect bracket. The modular molded interconnect includes at least one electronic circuit trace arranged thereon configured to interconnect a portion of a flexible printed circuit board and to support a portion of the flexible printed circuit board. The switching device is configured to contact portions of the at least one electronic circuit trace.

This is directed to a dome switch that may prevent liquid from coming into contact with circuit elements of the switch. A deformable dome may include a conductive inner surface region and may be placed over a conductive contact pad such that the dome may deform and the conductive elements may contact each other. At least one sheath may be positioned between the conductive region of the dome and the contact pad positioned below the dome for preventing liquid external to the one or more sheaths from contacting the conductive portions of the switch. In some embodiments, a first sheath may be coupled to the inner surface of the dome about the conductive inner surface region and a second sheath may be coupled to a mounting surface about the conductive contact pad, such that when a user deforms the dome, one of the sheaths may extend into the other sheath.

A switch module of built-in anti-surge disconnection structure mainly comprises an overcurrent protection switch and an anti-surge disconnection structure ingeniously built inside a heat-resisting housing. The switch module has a first connecting point and a second connecting point for operation. When overvoltage occurs, the temperature of at least one metal oxide varistor would instantly rise up to a degree higher than the melting point thereof, melting at least one thermo-sensitive piece, loosening at least one spring element, displacing a pushing element, and thus forcing the connecting points detaching from each other to turn off the switch and stop supplying the electricity power, so as to ensure more of electricity safety. Also, the switch module has the colloid thermo-sensitive piece directly fixing the spring element instead of having a band for fixing in the prior art, achieving an easier manufacturing process and better effectiveness of the switch module.
