(B3F-9jjj), refer to the above for-
ward current derating curve.
Dimensions
Note:
1. Unless otherwise stated, a tolerance of
±
0.4mm applies to all dimensions
2. No terminal numbers appear on the switches. To orient a switch in the “bottom view” position, turn it so that the terminals are on
the up and down sides and the word OMRON is right-side up.
