The invention relates to a switch including a switch housing, a contact system and a base disposed in the switch housing, a resistive element for diagnosing a state of a switch, and at least two terminals leading from the base. The resistive element has a specific resistance value. The resistive element is a conductive material formed on the base, the terminals being electrically connected by the conductive material.

A device such as, for example, an energy storage device or a micro-resistor, is disclosed which includes a silicon based electrode in which decreased interfacial resistance/impedance throughout the charge-mobile region of the device is provided. The decreased interfacial resistance/impedance is provided by forming an interfacial additive composite layer composed of a molten lithium containing salt layer and a layer of a Li-salt containing conductive polymeric adhesive material between the silicon based electrode and a solid polymer electrolyte layer. The presence of such an interfacial additive composite layer increases the ion and electron mobile dependent performances at the silicon based electrode interface due to significant decrease in the resistance/impedance that is observed at the respective interface as well as the impedance observed in the bulk of the device.

This invention provides a resin composition for preparing an allylphenol-maleimide copolymer used for a protective film for an electronic component including: (A) an allyl group-containing phenol compound having a rigid structure; (B) an N-aromatic maleimide group-containing compound having a rigid structure; and (C) an N-aliphatic maleimide group-containing compound having a flexible structure.

A force sensitive resistor includes first and second electrical contacts, and a layer of deformable material impregnated with carbon nanotubes. The layer of deformable material is arranged between the first and second electrical contacts. A difference in the conductivity of the impregnated material caused by deformation of the material is detectable across the contacts. A method of manufacturing a force sensitive resistor includes the steps of providing first and second electrical contacts, and arranging a deformable material impregnated with carbon nanotubes between the first and second electrical contacts. Again, a difference in the conductivity of the impregnated material caused by deformation of the material is detectable across the contacts.
