LAMPS

T-1³⁄4 incandescent lamps are available

from MICRO SWITCH in 28 volt versions.

LAMP ORDER GUIDE

Use of neon lamps is not recommended.

Light output is approximately 30% of an

incandescent lamp. Also, a neon lamp

will not illuminate blue or green filters or

display screens due to the absence of

these colors from the neon light spec-

trum.

LAMP POLICY

The 28 volt lamps are offered as a conve-

nience to customers. Honeywell MICRO

SWITCH Division does not extend any

warranty as to such lamps, and cannot

guarantee to provide lamps from specific

manufacturers. Any technical or quality

questions regarding such lamps should

be directed to the lamp manufacturer.

Wattage should not exceed 2.4 watts (2 lamps) per switch, for continuous illumination.

COLOR FILTERS FOR PROJECTED

SWITCH GUARD ACCESSORY

A hinged cover on the switch guard helps

avoid inadvertent operation of the display

screen. It is installed in place of the trans-

parent slide-on cap furnished with three-

piece screen. Note: When used with pull-

in coil devices, specify the 2C200 oper-

ator-indicator housings which have the

no-tool relamping feature.

0,0 = mm

0.00 = inches

Key:

Barrier mount assembly with guard in-

stalled. (Can also be used with all flange

mount units.)

Guard requires a ‘‘lift-to-push’’ response

to operate switch normally.
