Contact Blocks
Standard Contact Blocks—Molded, phenolic construction.
Enclosed silver contacts with reliability “nibs” that improve the
reliability of switching performance under dry circuit, corrosive
atmosphere and fine dust conditions. For more extreme
conditions, the logic level contact blocks described below are
recommended.
Logic Level Contact Blocks—Feature palladium contacts.
Palladium, which is more inert than gold, is well suited for
voltages and currents approaching zero. When mounted in an
enclosure rated for highly corrosive environments, logic level
contact blocks can be used where exposure to chemicals may
cause failure to other types of materials.
Mounting Limitations
See the contact block mounting limitations for Type E30
pushbutton and combination pushbutton and light operators on
this page. Mounting positions 1 thru 8 indicate single depth
contact blocks. Each of these positions can represent either a
single circuit 600 volt block or a two-circuit 120 volt block. The
two-circuit 600 volt block requires two of the numbered
positions shown.
