Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches”.
Stopper Installation
Do not use a Switch as a stopper. Be sure to install a stopper as
shown in the following illustration to ensure that the base of the
Operation Key does not strike the Head, and adjust the stopper to be
within the setting zone (0.5 to 3 mm) of the base of the Operation Key.
Do not subject the Switch to a shock that exceeds the Switch's shock
resistance of 1,000 m/s
The Switch contacts can be used with either standard loads or
microloads. Once the contacts have been used to switch a load,
however, they cannot be used to switch smaller loads. The contact
surfaces will become rough once they have been used and contact
reliability for smaller loads may be reduced.
Mounting Method
Appropriate Tightening Torque
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
• Do not use the Switch submersed in oil or water or in locations
• Always attach the cover after completing wiring and before using
• Do not switch circuits for two or more standard loads (250 VAC,
• Loose screws may result in malfunction. Tighten the screws to the

Securing the Door
When the door is closed (with the Operation Key inserted), the
Operation Key may exceed the set zone because of, for example, the
door's own weight, machine vibration, or the door cushion rubber.
Secure the door with a stopper so that the Operation Key remains
within the set zone.
