• Use 1.6-mm-thick glass epoxy PC board with drilled holes.
• Design a circuit so that the LB/LBW series can operate within the rated voltage and current range. Make sure that inrush current and voltage do
not exceed the rating.
• Minimum applicable load is 5V AC/DC, 1 mA on gold contacts. Applicable range is subject to the operating condition and load.
• Since the *2.8-mm-wide terminal touches the PC board as shown on the right, short circuit may occur with pattern lines. Design a circuit that
prevents short circuits.

Note 1: When designing, note the alignment of center lines of the contact blocks and center lines of the operators.
Note 2: The diameter of the terminal hole is ø1.2.
Note 3: Hole diameter may vary to meet installation requirements. Determine the location and the size of the hole so that the locking lever can be operated.
