Technical Terminology & Cautions for Use (Detection Switches)
TECHNICAL TERMINOLOGY
Detection Switches
A compact switch equipped with an enclosed micro-gap snapaction
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.
SPDT
SPSTN.C.
SPSTN.O.
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.
