Abstract

The load dependent switch is a safety device for a moving step is public transport vehicle. The switch is connected to movable components. When the load exceeds the tension of a spring it operates a circuit. The spring movement is limited by a stop. The switch (5) with its operating element (4) and the spring (3) are mounted in a telescoping chamber. The stop (6) is in the direction of applied load and consists of an abutment (7). The chamber (1) is formed of a tube (1a) with fixing flange (1b), an inward facing collar (1c), and a stopper (1d) screwing into it at the flange end. The inner part (2) has a U-shaped section with a collar (2a) complementing that of the outer tube.
