■ 特徴
Features
1. A s u p e r b s u r f a c e - m o u n t a b l e
illuminated switch integrated with one
or two LEDs into an ultra-compact
package.
2. One-color or two-color types are available.
The color of illumination can be a
combination of four: red, orange, yellow
and green. A non-illuminated type is also
available upon request.
3. The number of parts and time for
mounting are also reduced, resulting
in lower production costs.
