The present invention discloses a method using a bismuth based alloy as power-off element, comprising: a bismuth based alloy is used as the power-off element and a melting point of the bismuth based alloy is between 100 C. to 380 C.; when the power-off element is in an environment below the melting point, two conductive elements are mutually contacted and capable of conducting currents, whereas the power-off element is only receptive of the currents but does not serve as a medium for conducting the currents; when a working temperature of a switch or the socket is close to or exceeds the melting point, the power-off element loses rigidity and enables the two conductive elements to be separated from each other, thereby forming an electrically disconnected state.

A relay contactor is provided and includes a shaft assembly comprising a plate, which is movable between an open position at which the plate is displaced from leads and a closed position at which the plate contacts the leads and an actuation system configured to selectively move the plate into the closed position. At least one of the shaft assembly and the actuation system is configured such that, as the plate moves into and away from the closed position, a movement of the plate relative to the leads comprises at least a non-linear, rotational or an abnormally linear component.

A double-sided metal mesh conductive particle and a pushbutton having the double-sided metal mesh conductive particle. The double-sided metal mesh conductive particle includes a first metal mesh layer, a first adhesive layer, a base layer, a second adhesive layer, and a second metal mesh layer arranged sequentially from top to bottom; an upper surface of the first metal mesh layer has a multiple of first conductive bumps, and a lower surface of the second metal mesh layer has a multiple of second conductive bumps. The double-sided metal mesh conductive particle ensures a reliable contact with a circuit and provides a good electrical conductivity and a double-sided conduction. When the conductive particle is installed to a pushbutton with an electrical contact function, a double-sided conduction can be achieved to prevent the conductive particle from being installed in a wrong direction or affecting the electrical conductivity.
