Position sensor for escalators and moving walkways

A position switch biasing device comprising:

• a fastening element for fastening the position switch biasing device to a position switch, wherein the position switch comprises a button element which is configured to be displaceable in a first direction and is held in an OFF switch position by a spring element acting against the first direction;
• and
• a biasing element, wherein the biasing element is coupled to the fastening element so as to be linearly displaceable and arranged with the position switch such that, when the position switch biasing device is mounted on the position switch, the biasing element is movable telescopically in the first direction of the button element and the biasing element holds the button element of the position switch in a partially indented, biased state without the application of external force,
• wherein the position switch biasing device is configured to couple to a position switch to create a position sensor, wherein the position sensor is configured to monitor a gap between a base plate and a conveyor belt of an escalator or a moving walkway.
