Mounting directions of the LED/lamp for the pushbutton unit

(2) For the indicator:

Insert the LED/lamp guide into the narrower opening

in the indicator's receptacle.

(1) For the lighted type switch:

Fit the LED/lamp so that its guide projection is inserted into

the wider opening in the receptacle of the pushbutton unit.

Note: Push the LED/lamp projections into the base groove. The LED/lamp is flexibly mounted when used for illumination and is rigidly

mounted when used for indicators.

Removing lamp from the pushbutton unit

Position the functional unit as shown in (1). Press down on the

LED/lamp angling it in the direction indicated by A. Side B of the

LED/lamp disconnects and side C angles away from the

pushbutton unit so that it looks like (2). Turn the LED/lamp in the

direction indicated by D. The LED/lamp projections (2 locations)

will disconnect from the LED/lamp groove so that it looks like (3).

Pull in the E direction and remove the LED/lamp.

Mounting directions for the pushbutton unit and the switch unit

Insert the LED/lamp unit into the aperature of the switch unit with the LED/lamp

unit's guide facing the side of the aperature mouth that does not have the two

projections. The pressure applied during insertion should be 2.5 kg min.

Note: Since the mounting directions of the pushbutton unit are the opposite for

the lighted type switch and the indicator application, pay special attention

to the direction of the legend plate.

Removing the pushbutton unit

Pull the cap of the functional unit while holding the recessed guide

on both sides.

Note: Do not use radio pliers to remove the cap as they may cause damage.
