The 0-1 push-button panel with pilot light is the on/off control panel for Omega and Arsa brand slicers. It has two positions (0 = off, 1 = on) and a pilot light that indicates the machine is powered/running.

The push-button panel is the most heavily used electrical component on a slicer, since it is operated every time the machine is switched on: over time the internal contacts wear out or the membrane/button can stick or stop clicking positively. Typical failure symptoms are: the slicer does not start when pressing 1, the pilot light stays off even though the machine is running, or the button remains stuck in position. In these cases, replacing the panel restores correct operation and the safety of the machine.
