A switch for opening and closing optical connections between at least a pair of fiber-optical waveguides comprising a base body having a planar seating surface, a common retaining element being formed of a spring steel resting on the seating surface of the base body and having at least one slot to form a switch tongue integrally connected by at least one stay to a carrier part, at least two waveguides being secured on the same surface of the retaining elements so that when the tongue is in a first position engaging the seating surface, a closed optical connection between the waveguides will be obtained. Preferably, the switch is electromagnetically actuated to cause the tongue to move between a pair of positions with one position having the waveguides optically connected together and the other position having them out of connection. In one embodiment, waveguides are disposed on both surfaces of the retaining element so that the two pairs of waveguides are optically connected in one position and a bridging circuit between one waveguide of one pair and another waveguide of the other pair is obtained in the second position.
