Abstract:
A contact assembly for contacting a PTC resistor, comprising:a PTC resistor;contact elements that are asymmetrically structured, so that the contact elements lie against the PTC resistor offset relative to one another at mutually opposite lateral surfaces of the PTC resistor;the contact elements being integrally formed as one-piece elements of contact springs and prestressed parts, forces acting on the PTC resistor via the contact springs at mutually offset contact locations,the prestressed parts respectively exerting a force in the direction of the PTC resistor at respective locations that are arranged offset relative to the contact locations at the opposite side at which the force is exerted by the contact springs; andthe respective locations at the PTC resistor against which the prestressed parts exert a force being electrically insulated.
