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 components 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.
