TYPICAL APPLICATION
Frames snap into panel opening and are independent from switch mounting. Accurate positioning of the PC
mounted switch relative to the panel opening is necessary to provide proper clearance between actuator and
frame. Available in two basic styles and four panel thicknesses .047-.125 in. Material: Nylon. Finish: Matte.
