EPM Series Sealed Pushbutton Switches

meet high-performance needs for rug-

ged, compact size sealed switches that

are exposed to water, oil, cleaning sol-

vents, and many industrial chemicals.

They provide long, reliable operating life

under conditions of high shock and

vibration in severe environment applica-

tions.

Inadditiontobeingbuilttostanduptode-

manding environments, EPM switches

adheretogoodhumanfactorsprinciples.

Thedesign combineslowtravelwithhigh

tactile feedback and meets arctic glove

requirements. Raised barriers on the be-

zel enhance finger positioning and help

prevent inadvertent operation of two

abutting units at one push. Lighted dis-

play options provide further application

versatility.

LED ILLUMINATION

Long-life LEDs enable reliable illumina-

tion. They resist effects of shock and vi-

bration, reducing service and mainte-

nance requirements. (Unlighted versions

are also available.)

The following lighting functions can be

furnished: High-intensity display using

two LEDs to create a brilliant light signal

that can be distinguished under high am-

bient conditions, and/or a pair of LEDs

whichsoftlybacklightthelegendforview-

ing under low ambient conditions.

There is a choice of red, green or yellow

LEDs.Matchingindicators,whichprovide

lighted display only, complement the

switches to help present a uniform panel

design.

ELECTRICAL FLEXIBILITY

EPM switches can be furnished with one

or two SPDT basics. EPM22 electronic

control switches handle up to 1 amp,

EPM32 power duty switches up to 7

amps.

EASY TO INSTALL

Front panel hard-mounting is quick and

easy. Only a screwdriver is needed to

tighten the swing-out mounting lugs,

which securely lock and seal the unit in

thepanel.Thoughthecover/bracket sim-

ply snaps onto the housing, it has inher-

ent tamper resistance. The cover can be

removed intentionally with a small screw-

driver(orothertool)toaddorchangeleg-

ends.

EPM’s 3⁄4-inch square panel cutout on 1-

inch centers is suited to row, column, or

matrix arrays.

voltage with an appropriate series resistance be used to drive

the LEDs. This minimized the effect of temperature (current var-

iation) on forward voltage of the LEDs. The example below il-
