CONTACT RESISTANC E
The contact resistance is the electrical resistance measured at the terminals of the switch when
the contacts are closed. The resistance specifications refer to unwired switches in new condi-
tion. For silver-based contact materials this value is below 100 m#, in gold-based materials
below 50 m#.
SWITCHI NG S ECUR ITY
The highest switching security is obtained by utilizing from the entire pre-travel and over-travel.
Another element is the contact force which depends in turn on the actuating force. Switches
with high contact forces should be chosen if possible.
BOUNCE T IME
The bounce time is the time between the first closing of the contacts (turn-on signal) and the
last dropping below a given threshold value of the contact resistance. The values are typically
below 5 ms.
SWITCHI NG TI ME / TRAVEL
The switching time/travel is the time/distance that the switching system needs to get from the
first opening of the previously closed contacts to the first current flow of the contacts after the
snap action. Please ask for additional information for applications with a very slow actuating
speed or applications where the actuation of the switch is controlled by its switching process.

Free position Position of the actuator, without any influence of outside
force.
Operating position Position on the travel of the actuator, where the snap
mechanism is set into function.
Total travel position Position of the actuator at the end of the allowed travel.
Release position Position on the travel of the actuator, where the snap
mechanism starts to operate backwards.
Actuating force Necessary force at the actuator, to bring it from the free
position over the operating position.
Release force Force, to which the actuating force has to be decreased so
that the snap mechanism returns to the free position.
Force differential Difference between actuating force and release force.
Total over-travel force Necessary force, to keep the actuator in the permitted total
traveled position.
Pre-travel Movement between free position and operating position.
Over-travel Movement between operating position and total traveled position.
Return travel Movement between total traveled position and release position.
Release travel Movement between release position and free position.
Movement differential Movement between operating position and release position.
Total travel Sum of pre-travel and over-travel resp. return travel and
release travel.
