Using Switches for Microloads
Contact failure may occur if a Switch for a general load is used to
switch a microload circuit. Use Switches in the ranges shown in the
diagram below. However, even when using microload 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 60) (JIS C5003). The equation, λ 60 =
0.5×10
less than 1/2,000,000 operations with a reliability level of 60%.
Operating Environment
• The Switches are designed for use indoors. Using a Switch
• Do not use the Switch submerged in oil or water, or in locations
• Confirm suitability (applicability) in advance before using the Switch
• Do not use the Switch in the following locations:
• Use protective covers to protect Switches that are not specified as
outdoors may cause it to malfunction.
continuously subject to splashes of water. Doing so may result in oil
or water entering the Switch interior.
where it would be subject to oil, water, chemicals, or detergents.
Contact with any of these may result in contact failure, insulation
failure, earth leakage faults, or burning.
waterproof or airtight whenever they are used in locations subject
to splattering or spraying oil or water, or to accumulation of dust or
dirt.
• Locations subject to corrosive gases
• Locations subject to severe temperature changes
• Locations subject to high humidity, resulting in condensation
• Locations subject to severe vibration
• Locations subject to cutting chips, dust, or dirt
• Locations subject to high humidity or high temperature

contact failure, malfunction, or decrease in service life may be
caused by abrasive powder generated from the internal parts. If
excessive vibration or shock is imposed on the Switch, the contacts
may malfunction or become damaged.

load is minute. Otherwise, sulfuric film will be generated on the
contacts and contact failures may result. Use the Switch with gold-
