OVERTRAVEL TYPE : |
| |
The Overtravel Type is a limit switch which is provided with a greater OT to facilitate dog setting.
Since this type is indentical to the Basic Type in dimension, both types are interchangeable.

-71 series
The head of -71 series switch can be installed in any of the four directions:
45° operation on either side-possible
-72 series
The head of -72 series switch can be installed only in two directions, forward and backward:
