Note: 1. The indicator cover cannot be replaced on the molded terminals. In all cases the indicator does not light when the load is ON.
*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

2. Leakage current from indicator circuit may cause load's malfunction. Please check the load's OFF current before use the indicator-equipped switch.
The indicator covered if outsert molded
from diecast aluminum and has
outstanding sealing properties.
Operation (i.e., light-ON when operating
or light-ON when not operating) depends
on whether a neon lamp or 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°.
(Molded terminals cannot be switched in
this way.)

The indicator is either a neon lamp or
an LED. Models with LED indicators
have a built-in rectifier stack, so it is not
necessary to change the polarity.
The built-in switch's terminal screws
are used to connect the indicator
terminal. Since the connection spring
(coil spring) is used for this connection,
it will not be necessary to connect the
indicator terminal. When a ground
terminal is provided however, a lead
wire must be used.
