Features
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.
Spring small
plunger
Small
Medium
Large
Excellent
Used in much the same way as the pin plunger, but is easier to use because
the amount of movement after operation is larger.
Spring short
plunger
Small Medium Large
Good
Pin plunger is short, with large plunger diameter that makes centering easier.
Like small spring plunger, amount of movement after operation is large.
Panel attachment
plunger
Small
Large
Large
Good
Secured to panel with hex or lock nut; used as manual or mechanical plunger.
Amount of movement after operation is extremely large and operation point can
be adjusted by changing attachment position. Can be used in combination with
low-speed cam.
Panel attachment
roller plunger
Small
Large
Large
Possible
This is the panel attachment type with a roller, and can be used with fast-
moving cams and dogs..
Hinge lever
Large
Medium
Small
Little force required for operation. Appropriate for use with low-speed cams and
Possible 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
One way action
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.
Medium
Medium
Medium
Possible
This is hinge roller lever type, and can operate in relation to an operating unit
from a one way direction, but the roller is bent from the opposite direction and
cannot move.
This can be used to prevent reverse-direction action.
Leaf spring
Medium Medium Medium
Good
This has a leaf spring with offset yield force and has a large stroke. Ideal for
driving low-speed cams and cylinders. Fulcrum is fixed for high precision. To
prevent leaf damage, movement after operation must be within specified value.
Roller leaf spring Medium Medium Medium Good This is a leaf spring with a roller, and can be used with high-speed cams.

Excellent
This is used for low-speed, low-torque cams.
The lever comes in various shapes to fit the
operating body.
This is a reverse-action hinge lever with a roller
and is appropriate for cam operation. Excellent
resistance to vibration and impact when not
engaged.
This is a shorter version of the reverse-action
hinge lever with a roller and has a larger action
force, but is appropriate for cam operation with
a short stroke. Excellent resistance to vibration
and impact when not engaged.
The plunger is constantly
pressed down by a coiled
spring, and operating the
lever induces reverse action.
Because the plunger is
depressed when not
engaged, vibration and shock
resistance are excellent.
Pressing the plunger too far
does not cause abnormal
force to be applied to the
switch mechanism, so a
stable service life is assured.
