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°.
