Load voltage at ON = Power supply voltage – Residual voltage x 2 pcs.
= 24 V – 4 V x 2 pcs.
= 16 V
Example: Power supply voltage 24 VDC
Auto switch internal voltage drop 4 V
Load voltage at OFF = Leakage current x 2 pcs. x Load impedance
= 1 mA x 2 pcs. x 3 kΩ
= 6 V
Example: Load impedance 3 k Ω
Auto switch leakage current 1 mA

The indicator lights will light up when both
of the auto switches are in the ON state.
When two auto switches
are connected in series,
malfunction may occur
because the load voltage
will decrease in the ON
state.
The indicator lights will
light up when both of the
auto switches are in the
ON state.
(Solid state)
When two auto switches
are connected in parallel,
malfunction may occur
because the load voltage
will increase in the OFF
state.
(Reed)
Because there is no
leakage current, the load
voltage will not increase
in the OFF state.
However, depending on
the number of auto
switches in the ON state,
the indicator lights may
sometimes grow dim or
not light up, due to the
dispersion and reduction
of the current flowing to
the auto switches.
