Note: 1. Leakage current from indicator circuit may cause load malfunction (i.e., the load may remain ON). Make sure that the load operating
current is higher than the leakage current.
For countermeasures, refer to technical support on your OMRON website.
*1. Light-ON when operating means that the lamp lights when the Limit Switch contacts (NC) release, or when the actuator rotates or is pushed
down.
*2. Light-ON when not operating means the lamp remains lit when the actuator is free, or when the Limit Switch contacts (NO) close when the
actuator rotates or is pushed down.
Indicators
Indicator
The indicator is either a neon lamp or an
LED. Switches with LED indicators have a
built-in rectifier stack, so there is no
connection polarity.
Contact Spring
Use the terminal screws on the built-in
switch to connect to the lamp terminals.
A coil spring is used to make contact, so
connecting to the lamp terminals is not
necessary.
Indicator Covers
The indicator covered if outsert molded
from diecast aluminum and has outstanding
sealing properties.
Indicator Windows
Operating status (i.e., light-ON when
operating or light-ON when not operating)
depends on whether a neon lamp or an
LED is used.
Indicators can be switched from light-ON
when operating and light-ON when not
operating, by simply rotating the indicator
holder by 180°.
