AT506 NKK Switches

Power Rated Pushbuttons Series DLB Distinctive Characteristics Various cap styles and colors to meet differing application needs. Bright, full-face illumination to distinctively indicate status. Rear panel threaded mounting or snap-in mounter for front panel mounting. 5-amp power rating standard. Dry circuit capability available. Detent switching mechanism provides positive indication of actuation. Heavy gauge steel case protects switch compo- nents and increases durability. 1,500V dielectric strength between contacts and case is accomplished by clinching the frame away from the terminals. Solder lug and PC terminals staked into base.
