Short Body Pushbuttons
Series YB
BICOLOR LED & LED CAPS
Electrical specifications are determined at a basic temperature of 25 ° C.
LED circuit is independent of switch operation.
If the source voltage is greater than rated voltage, a ballast resistor is required. The ballast resistor calculation and more lamp
detail are shown in the Supplement; see Supplement Index (page Z1).
