TECHNICAL TERMINOLOGY

Technical Terminology & Cautions for Use

■

Detection Switches

A compact switch equipped with an enclosed micro-gap snap-
action contact mechanism that makes a specified motion with a
specified force to open/close a circuit, and an actuator outside
the enclosure (hereinafter referred to as the switch)

■

Actuator

A part of the switch that transmits the received external force to
an internal spring mechanism to move the movable contact so
that the switch can be opened and closed

■

Actuator stopper

A part of the switch to limit the actuator movement in the switch
operation direction

■

Rated values

Values indicating the characteristics and performance guarantee
standards of the snap-action switches. The rated current and
rated voltage, for instance, assume specific conditions (type of
load, current, voltage, frequency, etc.).

■

Mechanical life

The service life when operated at a preset operating frequency
without passing electricity through the contacts. (The life test is
performed at a switching frequency of 60 times/minute and
operating speed of 100 mm/second at the regular cam.)

■

Electrical life

The service life when the rated load is connected to the contact
and switching operations are performed. (The life test is
performed at a switching frequency of 20 times/minute and
operating speed of 100 mm/second at the regular cam.)

■

Contact form

This refers to the
components
determining the type
of application which
make up the electrical
input/output circuits in
the contact.

■

Insulation resistance

Resistance between non-continuous terminals, each terminal
and other exposed metal parts and between each terminal and
ground.

■

Dielectric

Threshold limit value that a high voltage can be applied to a
predetermined measuring location for one minute without
causing damage to the insulation.

■

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

Malfunction vibration ... 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

Shock durability ... Shock range where the mechanical shocks
received during snap-action switches transport and installation
do not damage the parts or harm the operating characteristics. 
Malfunction shock ... Shock range where a closed contact does
not open for longer than a specified time due to shocks during
use of the snap-action switches.
