TECHNICAL TERMINOLOGY

Technical Terminology & Cautions for Use

■ 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 snap-

action 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).
