The switches can be supplied in open execution or in sheet steel enclosure.
The switches are known for their versatile design, high making and breaking capacity, long mechanical and contact life and the many safety features that are provided.
Construction
The 3LAO switches are available in size 2 for 25 Amps. and size 6 for 63 Amps. They are made up of uniform switching packets assembled to form a stack. Each packet consists of 2 sets of contacts whose moving contacts
are operated by moulded plastic cams when the operating shaft is turned. The stacking of similar packets renders it possible to build switches for practically all types of small drives, offering at the same time a uniform appearance. This and their compactness make them ideal for installation
on machine tools.
