relay to control a high-capacity load if the Switch is connected to
such a load. (In this case, the exciting current of the relay coil is the

damage the Switch prematurely. If the switching frequency is too
high, the contacts may not be able to keep up with the speed.
The rated permissible switching speed and frequency indicate the
switching reliability of the Switch.
The life of a Switch is determined at the specified switching
speed. The life varies with the switching speed and frequency
even when they are within the permissible ranges.
Always conduct appropriate durability tests under actual condi-
tions before using a Switch.

Micro Load Applicable Range
Using a model for ordinary loads to open or close the contact of a
micro load circuit may result in faulty contact. Use models that
operate in the following range. However, even when using micro load
models within the operating range shown here, if inrush current
occurs when the contact is opened or closed, it may increase contact
wear and so decrease durability. Therefore, insert a contact
protection circuit where necessary.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability level
of 60% (λ
the estimated malfunction rate is less than 1/2,000,000 operations
