NKK LB26SGW01-E Standard size pushbutton Datasheet

Standard Size Pushbuttons
Series LB
Distinctive Characteristics
Square, round, rectangular, and round panel seal models
available.
Stainless steel clips provide secure mounting with a wide
range of panel thicknesses.
Latchdown feature gives indication of circuit status.
Audible and tactile feedback with smooth and
responsive operation.
Snap-action contact mechanism gives long electrical
life and sensitivity of actuation.
Combination solder lug and .110” quick connect
terminals are epoxy sealed to prevent entry of flux,
dust, and other contaminants.
Panel sealed model meets IP65 of IEC60529 specifications
(similar to NEMA 4 & 13).
Compact switch design minimizes behind panel depth.
Matching illuminated models available and shown in the
Illuminated Pushbutton section.
Matching indicators available and shown at the end of Section M.
