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.
