Lighted Pushbutton Switch
Lighted Pushbutton Switch with
Cylindrical 18-mm
×
8-dia. Body
Good illumination with even surface brightness.
Cylindrical body means panel cutouts can be made
easily.
Combines miniature design with excellent operat-
ing sensitivity.

Ordering Individually
Pushbuttons and Switches can be ordered separately. Combinations that are not available as sets can be created using individual Units. Also,
store the parts as spares for maintenance and repairs.

1. The above ratings are for an ambient temperature of 25°C.
2. The built-in LED lamp has no limiting resistor and so it is necessary to connect an external resistor within the range shown in the
above table. (For details of calculation formulas, refer to page 25.)
3. Refer to the characteristic graphs of V

on page 21.
4. The same LED lamp is used for both yellow illumination and white illumination and so the ratings are the same.
