Abstract

An arrangement for controlling an electric current comprises a main body (11), electrical main terminals (12a-b), a heating or cooling device (13), and a control device (14), wherein the main body has a temperature dependent electrical resistivity, the main terminals are electrically connected to the main body, the heating or cooling device is capable of heating or cooling at least a portion of the main body in response to which the main body gets heated or cooled and alters its electrical resistivity, and the control device is configured to control an electric current flown through the main body via the main terminals by means of controlling the heating or cooling device to heat or cool at least a portion of the main body. The arrangement can be used in a switch or an amplifier.
