Notes:
1 Operating point means the position whereat the switch assumes ON as a
result of rise of level, such position being represented by dimensions from
the pipe end.
2 Returning point means the position whereat the switch assumes OFF as a
result of fall of level, such position being represented by dimensions from
the pipe end.
