Abstract: An acceleration sensor (10) comprises a light transmitter (21) and a light receiver (37) arranged opposite each other on one optical axis (z). A tilting element (45) of axially symmetrical design, relative to the said axis (z), is arranged coaxially to the said axis (z) in a first operating position. It is provided with a passage opening (47) extending coaxially to the axis (z). Holding means (30, 31) serve for holding the tilting element (45) in a first operating position at a predetermined force in the direction of the axis (z). Guide means (27, 29, 31, 46, 48, 49) permit the tilting element (45), when an acceleration acts upon the tilting element (45), in a direction (x, y) perpendicular to the axis (z), to perform a limited tilting movement against the action of the predetermined force, about a center of rotation arranged at a distance from the axis, into a second operating position.

Abstract: A plug connection for light conductors comprises identical first and second hermaphroditic plug connector bodies, each connector body having a longitudinally-oriented light conductor guide section provided with a discrete light conductor guide means, and a longitudinally-oriented connector section adjoining the light conductor guide section at a radial plane and being provided with discrete snapping means. The snapping means provide for radially directed and opposite movement of the first and second connector bodies when detaching and joining the first and second connector bodies at their radial planes, thereby obviating the need for a cable allowance for conducting said joining and detaching movements.
