A membrane circuit structure having a plurality of switch regions includes first, second and third membranes and a spacer layer. The second membrane is beneath the first membrane, and a lower surface of the second membrane is provided with a conductive pattern in at least one of the switch regions. The spacer layer is disposed between the first and second membranes. The third membrane is beneath the second membrane, and an upper surface of the third membrane is provided with first and second trigger portions separated from each other in the at least one of the switch regions, and the conductive pattern is able to be in contact with the first and second trigger portions, so that the first and second trigger portions are able to be electrically connected to each other through the conductive pattern.

A sensor switch includes a ceramic body, first and second conductive units and a conductive member. The ceramic body includes intermediate, bottom and top layer assemblies cooperatively defining a chamber. The intermediate layer assembly has an intermediate layer inner peripheral surface. The bottom layer assembly has a bottom groove communicating with the chamber. The first conductive unit has a first conductive layer covering the intermediate layer inner peripheral surface. The second conductive unit has at least one second conductive layer disposed in the bottom groove. The conductive member is rollably disposed in the chamber for forming a current path with the first and second conductive layers.

An electromagnetic relay includes a fixed spring, a fixed contact configured to be swaged so as to be attached to the fixed spring, a movable spring, and a movable contact provided on the movable spring so as to be capable of making contact with the fixed contact, wherein a swaged portion of the fixed contact is formed so as not to protrude from a surface of the fixed spring.

The present invention generally relates to a mechanism for making the anchor of the MEMS switch more robust for current handling. The disclosure includes a modified leg and anchor design that allows for larger currents to be handled by the MEMS switch.

A toggle-type switch for a portable communications device includes a circuit board to be positioned within a cavity of a portable communications device. In one instance, the circuit board includes a first flank, a second flank disposed opposite the first flank, and a central rib disposed between the first and the second flanks. The circuit board has a non-planar shape, such that the first flank and the second flank are each offset relative to the central rib. The toggle-type switch includes a first electrical contact element coupled to the first flank, a second electrical contact element coupled to the second flank, and a projecting lever located above the central rib and between the first flank and the second flank. The projecting lever has a first leg to engage the first electrical contact element and a second leg to engage the second electrical contact element.

A circuit breaker comprises a contact and a line terminal configured that are bound in an assembly using a silver nanoparticles (NpAg) material that is synthesized by reducing a precursor salt in presence of a reducing agent. The contact comprises a silver alloy material having a first surface. The line terminal comprises a non-ferrous material having a second surface such that a plurality of drops of the silver nanoparticles (NpAg) material synthesized using a green chemistry process are applied in an interface between the first surface of the contact and the second surface of the line terminal by performing a resistance projection welding to bind the two components.
