Overall length: 26 mm max.
Power consumption: 2.6 W max.
When DC-specific LEDs are used, wire the Switch so that the X1
terminal is positive.
The LED lights with approx. 0.1 mA or less of micro-current. Take
a countermeasure like adding a resistor to prevent mis-lighting in
parallel to the LED.
The micro-current varies with the machine (leak current or stray
capacity between cables, etc.). Select resistance value and
allowable power consumption that meet the actual current.

Using the Microload
Contact failure may occur if a Switch designed for a standard load is
used to switch a microload. Use Switches within the application
ranges shown in the following graph. Even within the application
range, insert a contact protection circuit, if necessary, to prevent the
reduction of life expectancy due to extreme wear on the
contacts caused by loads where inrush current occurs when the
contact is opened and closed.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability
level of 60% (λ

cause malfunctions or damage to the Switch.
Also, most Switches are made from resin and will be damaged if
they come into contact with sharp objects. Particularly scratches
on the Operation Unit may create visual and operational
obtrusions.
Handle the Switches with care, and do not throw or drop them.
