Wiring
Do not connect the bare lead wires directly to the terminals but be
sure to connect each of them by using an insulation tube and M3.5
round crimp terminals and tighten each terminal screw within the
specified torque range.
The proper lead wire is 20 to 14 AWG (0.5 to 2.5 mm
Make sure that all crimp terminals come into contact with the casing
or cover as shown below, otherwise the cover may not be mounted
properly or the D4B-@N may malfunction.
Ordering Method
The D4B-@N uses a block mounting
method. Switches can be ordered either as
sets or as individual parts. If a set is
ordered, the Switch will be shipped with all
parts assembled.
Note: For Switches with Roller Levers, do
