Notes on replacing the LED Unit
• When replacing the LED unit, make sure that static electricity is not applied.
• Make sure that the LB series has cooled down before replacing the LED unit.
• To avoid getting burned, be careful not to touch the unit while it is still hot.
Notes on Using Quick Connect Terminals
1. Use #110 tab quick connects, 0.5 mm-thick.
2. When connecting the terminals on the left and center, make sure that
surfaces of the quick connects face each other. Otherwise, a short-circuit may
occur.

damaged if a force other than a horizontal force is applied.
Installing Rubber Boots
When using the switches in enviroments subject to splashing water or an exces-
sive amount of dust, make sure to use an optional rubber boot.
As shown in the drawing below,
j
remove the gasket from the operator, and
k
attach the rubber boot from the front (button side).
Standard Bezels
For rectangular and square units, pull out the seals of the rubber boot and place
them around the operator sleeve as shown below. Make sure that the seals are
not twisted or tucked inside and that the gasket is removed, otherwise water-
proof and dustproof characteristics are not ensured.
