Note: 1. Do not use the M12 mounting screw and the case mounting hole at the same time, or excessive pulling force will
              be imposed on the switch and the case and cover may be damaged.
           2. On the model Z-15GQ3-B, PT can be set to a value larger than that for the Z-15GQ.
           3. On the model Z-15GQ8-B, operating position can be adjusted by providing a screw in the plunger section.
           4. On the model Z-15GQ8-B, the M3 hole with a depth of 10 mm is a through hole. Take precautions so that no
                water or screw lock agent penetrates into the hole.

** The pin plungers of reverse-type models are continuously pressed by the actuator levers with compression coil
    springs and the pin plungers are freed by operating the levers. Reverse-type models are highly vibration- and shock-
    resistive because the pin plungers are normally pressed.
