MLU Switch

The MLU family uses a threaded glass-filled nylon housing which can be used in rugged environments. This housing can contain a Reed, Triac or Transistor sub.

TECHNICAL DESCRIPTION: (Top)

The most common reed only style switch typically incorporates a 100 VA reed. However, other reed sizes are available. These switches work in either AC or DC environments.

The Triac style switch uses a semiconductor device in conjunction with a reed to carry higher AC loads.

The Transistor style switch uses a transistor in conjunction with a reed to carry higher DC loads.

These switches are not prone to being over-ridden by tape, mechanical intervention, dirt, or ice. All switches are built with a UL PVC jacketed cable. A stainless steel hose may be added for additional protection (see Options).

Color-coded wires are used for easy installation.

For DC Transistor-style applications: Red Þ +DC, Black Þ -DC
