Example: Power supply is 24 VDC.
Internal voltage drop in switch is 4 V.
Load voltage at OFF = Leakage current x 2 pcs. x Load impedance
= 1 mA x 2 pcs. x 3 k = 6 V
Example: Load impedance is 3 k

The indicator lights will light up
when both switches are turned ON.
(Solid state)
When two 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 if both of the switches
are in the ON state.
When two switches are
connected in parallel,
malfunction may occur
because the load volt-
age will increase when
in the OFF state
