An electrical mains plug having a body formed of an electrically insulating material is described. Two contact pins are arranged parallel to one another and which project out of the body at a first side thereof, and inside the body are connected or can be connected in each case to an electrical conductor which leads out or can be led out of the body at a second side thereof. The thermal bimetallic element is provided as a temperature sensor, said thermal bimetallic element being a constituent part of the thermal bimetallic switch which is associated with at least one of two contact pins. An electrical connection cable suitable therefor and an electrical device connected thereto are also described.

A temperature-dependent switch has a housing with a cover part having a lower side and an upper side and with an electrically conductive lower part having a circumferential shoulder and a circumferential wall with an upper section that overlaps the cover part. The switch has a first external contact surface on the upper side of the cover part and a second external contact surface externally on the housing, wherein the upper section of the circumferential wall presses the cover part onto the circumferential shoulder. A temperature-dependent switching mechanism is arranged in the housing and, depending on its temperature, establishes or opens an electrically conductive connection between the first and second external contact surfaces. A circumferential cutting burr is arranged on the shoulder in the lower part.

A zero-power plasmonic microelectromechanical system (MEMS) device is capable of specifically sensing electromagnetic radiation and performing signal processing operations. Such devices are highly sensitive relays that consume no more than 10 nW of power, utilizing the energy in detected electromagnetic radiation to detect and discriminate a target without the need of any additional power source. The devices can continuously monitor an environment and wake up an electronic circuit upon detection of a specific trigger signature of electromagnetic radiation, such as vehicular exhaust, gunfire, an explosion, a fire, a human or animal, and a variety of sources of radiation from the ultraviolet to visible light, to infrared, to terahertz radiation.

Temperature-dependent switch, comprising a temperature-dependent switching mechanism having a switching mechanism unit, which comprises a movable contact part coupled to a bimetallic snap-action disc, and having a switching mechanism housing, in which the switching mechanism unit is arranged and held captively therein. Furthermore, the switch comprises a switch housing, in which the switching mechanism housing is arranged and held captively therein, wherein the switch housing comprises a stationary contact part, which acts as a mating contact to the movable contact part. The switching mechanism housing comprises an electrically conductive first base body and the switching mechanism is configured so as, below a response temperature of the bimetallic snap-action disc, to keep the switch in a low-temperature position in which the switching mechanism establishes a first electrical connection via the movable contact part between the first base body and the stationary contact part, and, if the response temperature is exceeded, to bring the switch into a high-temperature position in which the switching mechanism interrupts the first electrical connection. The switch further comprises a PTC component, which is electrically connected parallel to the first electrical connection.
