CAUTIONS
1. When the switch is to be used in plac-
es where oil or is abundant, bore a drain
hole in the bottom of the terminal cover.
2. Avoid places where highly acid or alkaline
fluids are used or high temperatures prevail.
3.Wiring
(1) Remove the terminal cover with a
v
driver.
(2) Insert the lead wire through the
knock-out of the terminal cover.
(3) Connect the lead wire to the terminal.
When connecting the terminals with the
fasten lug, those with the insulation
sleeve are recommended.
(4) The terminal cover can be mounted in
both directions.
N.C.
COM
In this case, fasten the terminal cover in
the opposite direction.
•Forepoxy-sealedterminaltypes,there
are two types by the cord outlet direction;
N.C. side and COM side.
4. Flexible rod type
(1) Put the detective object to the tip of
plastic part.
(2) Avoid pushing the tip of actuating
spring in the direction of axis. In the plac-
es of oil or water splashes and much
dust area, use the limit switch with keep-
ing the actuating spring in the vertical
direction.
