Technical Terminology & Cautions for Use (Operation Switches)
TECHNICAL TERMINOLOGY
Rated values
Values indicating the characteristics and performance guarantee
standards of the switches. The rated current and rated voltage, for
instance, assume specific conditions.
Electrical life
The service life when the rated load is connected to the contact and
switching operations are performed.
Mechanical life
The service life when operated at a preset operating frequency
without passing electricity through the contacts.
Dielectric strength
Threshold limit value that a high voltage can be applied to a
predetermined measuring location for one minute without causing
damage to the insulation.
Insulation resistance
This is the resistance value at the same place the dielectric strength
is measured.
Contact resistance
This indicates the electrical resistance at the contact part.
Generally, this resistance includes the conductor resistance of the
spring and terminal portions.
Vibration resistance
Vibration range where a closed contact does not open for longer
than a specified time due to vibrations during use of the snapaction
switches.
Shock resistance
Max. shock value where a closed contact does not open for longer
than a specified time due to shocks during use of the switches.
Allowable switching frequency
This is the maximum switching frequency required to reach the end
of mechanical life (or electrical life).
Temperature rise value
This is the maximum temperature rise value that heats the terminal
portion when the rated current is flowing through the contacts.
Actuator strength
When applying a static load for a certain period on the actuator in
the operation direction, this is the maximum load it can withstand
before the switch loses functionality.
Terminal strength
When applying a static load for a certain period (in all directions if
not stipulated) on a terminal, this is the maximum load it can
withstand before the terminal loses functionality (except when the
terminal is deformed).
