■ 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

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.
