Auto Switch Hysteresis
Hysteresis is the distance between the position at which slider movement
operates an auto switch to the position at which reverse movement turns
the switch off. This hysteresis is included in part of the operating range
(one side).

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.

When two auto switches are connected in parallel, malfunction
may occur because the load voltage will increase when in the
OFF state.

Load voltage at ON = Power supply voltage – Residual voltage x 2 pcs.
= 24 V – 4 V x 2 pcs.
= 16 V
Load voltage at OFF = Leakage current x 2 pcs. x Load impedance
= 1 mA x 2 pcs. x 3 kΩ
=6V
Example: Power supply is 24 VDC
Internal voltage drop in auto switch is 4 V.
Example: Load impedance is 3 kΩ.
Leakage current from auto switch is 1 mA.

Incorrect Usage
LJ1
Caution
LG1
1. Do not operate beyond the rated voltage range.
If applying voltage over the rated voltage range, equipment
may be damaged.
LTF
2. Avoid incorrect wiring such as polarity of power
supply.
LC1
Otherwise, equipment may be damaged.
LC7
3. Do not short circuit the load. (Do not connect to
power supply.)

1. Power lines and high voltage lines should not be in
the same piping or duct with wiring of the photo
micro sensor, as the system may malfunction or be
damaged due to induction. Separate wiring or
individual piping is required to avoid such trouble.
2. If operating with a small induction load such as a
relay, wire as shown in the figure below. (In this
case, be sure to connect a reverse voltage
suppression diode.)
