CAUTIONS
1. When overtravel is too large, life is short-
ened due to possible damage to the mech-
anism. Please use in the following appropri-
ate range.

2. Because these switches are not of
immersion protected construction, their use
in water or oil should be avoided. Also,
locations where water or oil can normally
impinge upon the switch or where there is
an excessive accumulation of dust should
be avoided.

3. The use of these switches under the fol-
lowing conditions should be avoided. If the
following conditions should become neces-
sary, we recommend consulting us first.
•Use where there will be direct contact with
organic solvents, strong acids or alkalis, or
direct exposure to their vapors.

high level under practical conditions of use,
the actual operating conditions should be
checked for the benefit of the quality of the
product.

5. Remote wire control types:
Because the main unit is not of water resis-
tant or immersion-proof construction, their
use in water or oil should be avoided. Also,
locations where water or oil can normally
impinge upon the switch or where there is
an excessive accumulation of dust should
be avoided. The main unit should be
installed above the detection part in such
case. (An actuator is immersion-protected
construction.)
6. Mounting
Three cover screws should be fasten uni-
formly. The rubber for opening cord should
be corrected as normal condition after con-
necting the wire.
7. How to change the indicator holder.
1) As shown in the photograph, wrench a
minus-driver in the gap between the cover
and the part of the indicator holder indicat-
ed by the arrow in the direction of insertion,
and raise the lamp a little.
2) After removing the indicator holder,
insert it in the reverse direction, and push it
in until a snap is heard.

3) After changing the direction of the indica-
tor holder, put the cover on it in such a way
that the spring touches the top of the termi-
nal screw.
(Unless the spring rests completely on the
terminal screw, distortion of the spring, fail-
ure in lighting of the lamp or short circuit
may result.)

8. Matters to be attended to in using spring
type VL Limit Switch with indicator.
1) When loads are connected to both N.O.
and N.C. only the indicatin at non-operation
time can be used.
2) Take special care not to damage or
deform the contact spring during change of
indicator holder direction or during connec-
tion work.
3) In the case of VL Limit Switch with Neon
lamp, if the indicator is connected in series
in a 100V circuit, the indicator ceases to be
lighted.
However, for a 200V circuit, up to 2 lamps
can be connected in series.
9. Matters to be attended to in using lead
wire type VL with lamp.
1) When loads are connected to both N.O.
and N.C. indication can be given on both
N.O. and N.C. sides, but it is impossible to
connect the indication circuit to the load in
series.
