LB25RKG01-A

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.
