Load voltage at ON = Power supply voltage – Residual voltage x 2 pcs.
= 24 V – 4 V x 2 pcs.
= 16 V
Example: Power supply is 24 VDC
Internal voltage drop in auto switch is 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 is 3 kΩ.
Leakage current from auto switch is 1 mA.

The indicator lights will light up when
both auto switches are turned ON.
When two auto switches
are connected in series, a
load may malfunction
because the load voltage
will decline when in the ON
state.
The indicator lights will light
up when both of the auto
switches are in the ON
state.

(Solid state auto switch)
When two auto switches
are connected in parallel,
malfunction may occur
because the load voltage
will increase when in the
OFF state.
(Reed auto switch)
Because there is no
current leakage, the load
voltage will not increase
when turned OFF.
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.
