    • A protective element for protecting in particular an electric motor against overload currents includes in a polymer matrix, preferably ETFE, for example 40% (by volume) of a first powdered filler of a conductive material, preferably TiB2, so that, as in the case of a PTC element, the resistance increases abruptly at a switching temperature corresponding to the melting temperature of the polymer. Also added are 20% (by volume) of a second powdered filler, a phase transition material which, at a critical temperature below the switching temperature, undergoes a phase transition in which it absorbs heat of transformation. As a result, the response time (T) of the protective element is notably extended in a range of the overload current factor (F) corresponding to higher permissible motor starting currents. Examples of materials which come into consideration for the second filler are those with a solid-solid phase transition such as pentaerythritol, NaNO2, NaNO3 or else with a solid-liquid phase transition such as UHMWPE, quinol or, in particular, microencapsulated metals, alloys and salts.

    • The nonlinear resistor has varistor behaviour and has a matrix and a filler in powder form which is embedded in the matrix. The filler contains sintered varistor granules with predominantly spherical particles of doped metal oxide. These particles are made up of crystalline grains separated from one another by grain boundaries. The filler also contains electrically conductive particles, which cover at most a part of the surfaces of the spherical particles, and/or the varistor granules contain two fractions of particles with different sizes, of which the particles in the first fraction have larger diameters than the particles in the second fraction and are arranged essentially in the form of close sphere packing and the particles in the second fraction fill the interstices formed by the sphere packing. The resistor can be produced straightforwardly and cost-effectively and is distinguished by a high nonlinearity coefficient, which is desired for a good protection characteristic, and by a high power acceptance.

    • A micro-electromechanical system comprises a substrate (S) and at least two micro-elements (1, 2) of which a first is bistably switchable. The micro-elements (1, 2) have faces (3a, 4a) facing one another, which are produced by a structuring method and thereby initially have at least one minimal distance from one another characteristic of the structuring method. The first micro-element (1) is then switched to the other stable state (B) whereby the distance between the faces (3a, 4a) facing one another is smaller than the characteristic minimal distance for the structuring method. The micro-electromechanical system can be constructed as an electrostatically actuatable microswitch with improved switchability. Laterally and horizontally operating micro-electromechanical systems with new functionality and current-free closed relays can be implemented.

    • A microswitch produced from a predominantly plate-shaped substrate can include: a stationary contact piece (7, 9) on the substrate, a moveable contact piece (6), which electrical contacts the stationary contact piece (7, 9) in the switch-on position of the switch and is electrically isolated from the stationary contact piece in the switch-off position of the switch, a bendable contact carrier (1) which holds the moveable contact piece (6) and is fixed to the substrate by two ends (2, 3), and a drive (10) which guides the contact carrier (1) into the switch-on or switch-off position by elastic deformation. The contact carrier (1) can deform in substrate-parallel fashion. In a stable position corresponding to the switch-off position, the contact carrier (1) has the form of a symmetrical antinode. In a stable position corresponding to the switch-on position, the contact carrier (1) is deformed in the manner of an asymmetrical antinode.
