A3C Lighted Pushbutton Switch

Cylindrical 12-dia. Series with Superb
Operability, High Visibility, and Compact Housing

  • Three models of Pushbuttons (round, square, and rectangular), two types of light-emitting elements (LED lamp and incandescent lamp), and two types of Switches (switching standard loads and microloads) available.
  • Models that can be used as an indicator also available.
  • Requires only 20 mm mounting depth
  • Efficiency in wiring improved by terminals arranged on the same surface.
  • All LED lamps, incandescent lamps, caps, and legends replaceable without tools.
  • UL (E41515) and CSA (LR45258) approved.
