2. If the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after coating.
Note: 1. Make sure the thickness of the mounting panel is 0.5 to 3.2 mm. If, however, a Switch Guard or Dust Cover is used, the
thickness of the mounting panel must be 0.5 to 2 mm.

Precautions
Refer to the Technical Information for Pushbutton Switches (Cat. No. A143) and the Precautions section for the A16.
■Correct Use
Mounting
When mounting the Case onto the Socket Unit, ensure that the orien-
tation is correct. Perform mounting with the • mark on the Case and
the TOP mark on the Socket Unit facing in the same direction.
Wiring
When using stranded wire, gather the ends of the strands together
before wiring.
When wiring, insert the wire until it comes into contact with some-
thing. After wiring is completed, pull on the wires to confirm that they
are connected securely.
After wiring, ensure that continuous pressure is not applied to the ter-
minals.
Refer to internal connections diagrams and confirm the terminal
numbers before performing wiring.
Screw-Less Clamps
Mounting Procedure
1. Strip a length of 10 mm off the end of the wire (allowable range:
10±1 mm).
2. Bunch wire strands together and straighten them.
3. Insert the wire into the insertion hole while pressing the release
button at the side of the hole. (Using a precision screwdriver is
recommended.)
4. Let go of the release button to lock the wire into place.
5. After locking, pull on the wire gently to confirm that it is securely
locked.
Removing Procedure
Remove wires by pulling them while pressing the release button.
Note: When reusing wires that have already been locked, cut off the
end of the wire and strip the wire again before using.
