■ 特徴/
Features
1. 小型であるため実用上のレイアウト
の融通性が高く、
他のコンポーネント
との共用により大きな自由度を与え、
セット設計が容易に行えます。
2. LEDはスイッチのサイドに配½され
ますが、
1個(1色×1個)、
2個(2色×
各1個 又は1色×2個)の内蔵が可½
です。
3. リフロー炉によるはんだ付けが出来
ます。
1. Compact size allows outstanding
flexibility of layout and freedom of
application, in combination with other
devices. Set design is now much
easier.
2. LEDs are located in each corner of
the switch the following internal
configurations are possible : One
LED (one of one color), or two LEDs
(two of one color or two colors with
one LED of each).
3. Reflow soldering is possible using a
reflow furnace.
