FEATURES High-intensity LEDs indicate status changes brilliant color display distinguished even under high ambient lighting conditions Soft-glow backlighted legends ambient viewing Rugged sealed construction withstands effects shock vibration provides dependable switching/lighted display severe environment applications Designed comply with MIL-S-22885 Suitable NEMA enclosures travel (.030 max.), with tactile feedback definite feel switching action
Series
Front-of-panel, hard mounting Compact size Field-replaceable legends recognized, certified, MILS-8805 qualified basic switches EPM22 electronic control EPM32 power duty switching electrical flexibility Matching EPM41 indicators uniform panel appearance Choice housing styles: Type Standard sealed housings Type Enhanced sealed housings with filters vehicle lighting security, designed MIL-STD-461 (EMI shielding), compliance AR70-71
Series Sealed Pushbutton Switches meet high-performance needs rugged, compact size sealed switches that exposed water, oil, cleaning solvents, many industrial chemicals. They provide long, reliable operating life under conditions high shock vibration severe environment applications. addition being built stand demanding environments, switches adhere good human factors principles. design combines travel with high tactile feedback meets arctic glove requirements. Raised barriers bezel enhance finger positioning help prevent inadvertent operation abutting units push. Lighted display options provide further application versatility. ILLUMINATION Long-life LEDs enable reliable illumination. They resist effects shock vibration, reducing service maintenance requirements. (Unlighted versions also available.) following lighting functions furnished: High-intensity display using LEDs create brilliant light signal that distinguished under high ambient conditions, and/or pair LEDs which softly backlight legend viewing under ambient conditions. There choice red, green yellow LEDs. Matching indicators, which provide lighted display only, complement switches help present uniform panel design.
ELECTRICAL FLEXIBILITY switches furnished with SPDT basics. EPM22 electronic control switches handle amp, EPM32 power duty switches amps.
EASY INSTALL Front panel hard-mounting quick easy. Only screwdriver needed tighten swing-out mounting lugs, which securely lock seal unit panel. Though cover/bracket simply snaps onto housing, inherent tamper resistance. cover removed intentionally with small screwdriver other tool) change legends. EPM's 3/4-inch square panel cutout 1inch centers suited row, column, matrix arrays.
CONSTRUCTION Insert furnished with without legends. legends backlighted, darker colors recommended insert. Black provides maximum contrast lighted legend displays. Diffuser plates specified lighted legend devices coated underside even illumination. When unlighted legends specified, diffuser plates molded from opaque plastic interchangeable with those used lighted legends.
