(Snap-action, Detection and Interlock Switches)

TECHNICAL TERMINOLOGY

Technical Terminology & Cautions for Use

■ Snap-action 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.
