What this cam switch does
The A3SSDA-6AAB-111: This is a 3-position maintained cam switch with 1NO-1NC contacts, used to manually select and hold operating modes in control circuits. The maintained action means the selected position stays latched without requiring continuous operator pressure — typical for selector switches on panel doors or machine control stations.
Replacement planning
For a BOM replacement, cross-reference the contact configuration (1NO-1NC) and the 3-position maintained switching function within the ABB cam switch portfolio.
