MICRO-LIMIT SWITCHES
DEFINITIONS OF TERMS
Free position
Position of the switch actuator when no force is
applied.
Back travel
The distance between the overtravel and release
positions.
Operating position
The position of the actuator when the contact snaps.
Total travel
The sum of pretravel and overtravel.
Overtravel position
The final position of the actuator.
Operating force
The force required to cause snap action of contact.
Release position
The position of the actuator when the contact snaps
back from the operating position to original position.
End operating force
The force to be applied to keep the actuator in the
allowed final position.
Contact opening gap
The distance between the open contact pair.
Release force
The force applied to the actuator at the moment the
contact snaps back from the operating position.
Pretravel
The distance between free and operating positions.
Overtravel
The distance the actuator travels after the contact
actuates.
Movement differential
The distance from the operating to release position of
the actuator.
H
Free travel
The distance between the release and free positions.

Micro-limit pushbutton switches are used in many applications including microwave ovens,
vending machines, copy and fax machines, medical and security equipment, computer peripherals
and many others. They are characterized by close tolerance precision switching positions and long
service life. APEM micro-limit switches are 100% electronic tested prior to shipment to insure
proper operation and conformance with specifications.
