The DIALIGHT 271-3111 is a classic panel mount indicator designed for use with MIL-P-7788 plastic panels. It is intended for front mounting in a 15/32 clearance hole and features a translucent panel edge lighting design. The indicator utilizes a brass mounting bushing with a cadmium plated finish, internal-tooth lockwasher and hex nut hardware, and solder terminals with a hot-tinned finish. An anti-rotation notch on the flange prevents rotation during tightening. The shank of the lens holder is crimped to secure the lamp. This part meets applicable requirements of MIL—L7806, MIL—L—3661B & MS25010 — Revision D.
