CN-0271 Change Notice B Series Change to B Illuminated Toggles LED Specifications Type of Change: Engineering Product Part Number Appearance The B Illuminated Toggles will have a change to the LED specifications for Red, Amber, Green, and bicolor Red/Green. The change will effect all illuminated models, both standard and custom. The specification changes are outlined below, followed by effected standard part numbers. LED Changes for B Illuminated Toggles LED COLORS & SPECIFICATIONS LEDs are supplied as an integral part of illuminated devices and are not available separately. The electrical specifications shown here are determined at a basic temperature of 25°C.
