I don't like the original design of the Trust AMST-606 window sensor, in addition it was to "fat".
This is a much thiner and modern design.
Sensor housing:
Close the magnet sensor with the original screw (counterbore necessary). Magnet housing:
Remove the magnet from the original housing and insert it into the new magnet holder
