LS20 シリーズ

Illuminated Type

LS20 Series

■ 特徴／

Features

1. 従来のSMD(表面実装デバイス)タイ

プのスイッチとLEDを1つのケース

内にパッケージした画期的な超小型

照光式スイッチです。

2. 2色発光タイプと単色発光タイプが

あり、

色も自由に組み合わせできます

(ご希望によっては、

照光なしのタイ

プも納入可½です。

)

3. マウント時間、

並びに部品点数の削除

ができ、

大幅なコストダウンが期待で

きます。

1. The superb surface-mountable

illuminated switch integrated with an

LED or two LEDs into super-miniature

package.

2. One-color or two-colors type is

available. The color of illumination

can be a combination of four:red,

orange, yellow and green. Non-

illuminated type is also available upon

request.

3. The mounting space can be greatly

reduced, while allowing higher

density mounting. In addition, the

number of parts and time for

mounting onto the substrate are also

reduced,resulting in lower production

costs.
