■ 特徴

Features

1. The compact size allows high layout

flexibility and freedom of application in

combination with other components,

making set design easy.

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.

3.8(L)×3.4(W)×2.5

（H）

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できま

す。
