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.

7. 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.
Three cover screws should be fasten uni-
formly. The rubber for opening cord should
be corrected as normal condition after con-
necting the wire.
6. 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.
8. 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.
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.)
