An electric power tool comprises one or more optical waveguides which are combined with a shaped body so as to form a support element having a stable shape. The light guides may be part of optical switches or sensors. The support element ensures protection of the optical waveguides from vibrations, dust and so on, whereby a high level of operational reliability is ensured.
