Eaton NSB C22S-DLH-R-K01-120 Pushbuttons Illuminated

Eaton NSB C22S-DLH-R-K01-120 illuminated pushbutton combines a red indicator with a single normally closed (1NC) contact and is rated for 120V operation. This device from the NSB family is designed for control applications in industrial equipment, delivering a visible signal when the circuit is energized while providing a simple single-contact input. The 1NC configuration means the contact is closed in its default (unactuated) state and opens when the button is pressed, offering a straightforward way to implement stop/interlock-style logic in 120V control circuits. The red illumination enhances visibility in dim environments, helping operators confirm the button state at a glance and reducing mis-operation in busy control panels. The part number C22S-DLH-R-K01-120 identifies this specific red-illuminated, 1NC variant within Eaton’s NSB pushbutton lineup, ensuring compatibility with other NSB components in the same control system. Use cases typically involve manual control points in machinery where a clear, illuminated stop or reset indication is desirable.
