Series Connection of Switches
The Solid-state Output-type Switches must not be connected in
series. To obtain the same effect as a series connection, form an AND
gate with a relay inserted between the Switch and load.
Parallel Connection of Switches
Connection to Power Source
The core wire colors have been changed to meet new standards. Make sure
that the wires are connected correctly.
• In principle, two or more D5A's should not be used in an OR
• However, they can be connected in parallel provided that both

configuration.
switches A and B in the above figure do not operate at the same
time and that the load does not have to be kept energized. In this
circuit, however, the leakage current is increased, multiplied by the
number of Switches connected in parallel. Consequently, the
Switch may not release properly. To keep the load energized,
connect a relay to each of the Switches as shown below.

Switch may be damaged.
negative sides, respectively, of the power source. Although the
D5A will not be damaged even if the polarity is reversed by mistake,
if this happens, the Switch maintains the ON state (i.e., the contact
is kept open) regardless of the presence or absence of the object
to be detected.
