Precautions for All Switches
Note: Refer to the Safety Precautions section for each Switch for specific precautions applicable to each Switch.
■ Precautions for Safe Use
• If the Switch is to be used as a switch in an emergency stop circuit
• Do not perform wiring while power is being supplied. Wiring while
• Keep the electrical load below the rated value.
• Be sure to evaluate the Switch under actual working conditions
• Do not touch the charged Switch terminals while the Switch has
• If the Switch has a ground terminal, be sure to connect the ground
• The durability of the Switch greatly varies with switching conditions.
• Maintain an appropriate insulation distance between wires
• Some types of load have a great difference between normal current
• The user must not attempt to repair or maintain the Switch and
• Do not attempt to disassemble or modify the Switch. Doing so may
• Do not drop the Switch. Doing so may result in the Switch not
Wiring
Pay the utmost attention so that each terminal is wired correctly. If
the terminal is wired incorrectly, the Switch will not function.
Furthermore, not only will the Switch have a negative influence on
the external circuit, the Switch itself may become damaged or burnt.
or in a safety circuit for preventing accidents resulting in injuries or
deaths, use a Switch with a direct opening mechanism, use the NC
contacts with a forced release mechanism, and set the Switch so
that it will operate in direct opening mode.
For safety, install the Switch using one-way rotational screws or
other similar means to prevent it from easily being removed. Protect
the Switch with an appropriate cover and post a warning sign near
the Switch to ensure safety.

terminal to a ground wire.
Before using the Switch, be sure to test the Switch under actual
conditions. Make sure that the number of switching operations is
within the permissible range.
If a deteriorated Switch is used continuously, insulation failures,
contact welding, contact failures, Switch damage, or Switch
burnout may result.

and inrush current. Make sure that the inrush current is within the
permissible value. The greater the inrush current in the closed
circuit is, the greater the contact abrasion or shift will be.
Consequently, contact welding, contact separation failures, or
insulation failures may result. Furthermore, the Switch may become
broken or damaged.
