1. The ON/OFF circuit for the guidance
load may suffer contact damage due to
surges or inrushes when the power is
turned either ON or OFF.
Consequently, insertion of a protective
circuit as per the following diagram is
recommended, in order to protect the
contacts.
2. Do not connect either irregular poles
or power sources to a switch contact.
Power connection examples (irregular
pole connection)
3. Avoid circuits where power may find
a way between the contact points (as
this may cause welding.)

Cautions for use
(1) r must be a minimum
of 10
;
(2) When using AC power:
Q Impossible when R
impedance is large.
W Possible when c, r
impedance is suffi-
ciently small com-
pared with R imped-
ance.
Can be used with both
AC and DC as appro-
priate.

4. Using electronic switch circuits (low
power, low current)
1) Bouncing and chattering are gener-
ated due to collision between the con-
tacts when the limit switch is switching
between them, and this sometimes
causes such problems as white noises
and error pulses in both the electronic
circuit and the reverberation equip-
ment.
2) If the generation of bouncing and
chattering becomes a problem, it is
necessary to consider installing a CR
circuit or other absorption circuit given
the circuit design.
3) This is particularly necessary when
high contact reliability is needed, and
is unsuitable for silver contact switch-
es. Switches with gold contacts pos-
sess excellent performance.
