Features
Pin plunger
Small
Small
Large
Out-
standing
Appropriate for linear short-stroke action. Pin plunger acts directly on snap
action mechanism, enabling high-precision positioning. Amount of movement
after operation is smallest among all of the actuators, however, so reliable
stopper is required.
Hinge lever
Large
Medium
Small
Possible
Little force required for operation. Appropriate for use with low-speed cams and
dogs; has large stroke.
Lever available in various shapes to fit operating unit.
Simulated roller
lever
Large
Medium
Small
Possible
Tip of hinge lever is bent into a semi-circle, enabling use as a simple roller type.
Leaf lever
Large
Large
Small
Excellent
Play in lever is used to assure maximum stroke. Construction provides for
space where lever is attached, for outstanding resistance to freezing.
Hinge roller lever
Large
Medium
Small
Possible
This is a hinge lever with a roller, and can be used with high-speed cams and
dogs.
The force required for pin plunger action is lighter than that of the lever, and the
stroke is longer.
