Note: 1.
Do not allow the load current to exceed the rated value.
          2. The contact ON/OFF timing is not synchronized. Confirm performance before application.

          3. Once the contacts have been used to switch a load, however, they cannot be use
d to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced.
