Abstract
An electrical contact unit comprises a flexible semiconductor, e.g. silicon, filament carrying contacts and having a shorted pn junction. The filament is mounted in a magnetic field. When light is directed on to the junction, e.g. from an optical fiber, the induced photo current flowing around the short circuit interacts with the magnetic field so as to bend the filament so as to establish connection with one or more adjacent fixed contacts.
