Down - NKK Switches

Short Body Pushbuttons
Series YB
Distinctive Characteristics
Full face or spot illumination with incandescent lamps or multi-element LEDs,
with or without resistors.
Choice of super bright LEDs in white, green, and blue as well as
bright LEDs in red, amber, and green.
Combination bezel-barrier is an integral part of the
switch and prevents accidental actuation.
Unique, patented thermoplastic elastomer seal
inside caps plus rolled sleeve of nitrile butadiene
rubber at joining of housing and inner case, all
for added protection to interior mechanism.
Dust and oil tight as well as splashproof panel seal
models qualify to IP65 of IEC529 Standards
(similar to NEMA 4 and 13). Panel seal models
provided with exterior o-ring.
Distinctive design of snap-action contacts for shock
resistance, long life, and sensitive actuation.
High density design to give behind panel depth
of less than one inch.
Tin-lead plated terminals are epoxy sealed to lock out flux, dust,
solvents, and other contaminants.
Latchdown for indication of circuit status, plus audible, tactile
feedback with smooth, responsive operation.
Actual Size
Nonilluminated models available and shown in the Pushbutton
section.
Matching indicators available and shown in the Indicator section.

Electrical Specifications
Electrical specifications are determined at a basic temperature of 25°C. Lamp circuit is independent of switch operation.
For dimension drawing of lamp see the Accessories & Hardware Index (page Y1).
If the source voltage is greater than rated voltage, a ballast resistor is required.
The ballast resistor calculation and more lamp detail are shown in the Supplement; see Supplement Index (page Z1).
