ACDC 40A 2P Three Position Change Over

Three positions (I-0-II) — selects source 1, off, or source 2

2-pole switching — switches two conductors simultaneously (common for dual supply systems)

Rated current: 40 A — suitable for many loads or supply switching duties

DIN-rail or panel mount options — modular or enclosed types available

Mechanical and electrical durability — robust mechanism to handle repeated switching

Safe isolation — ability to fully disconnect circuit when in “0” position

Suitable for AC / DC use (depending on model spec) — check voltage rating for your system

Clear labeling and position indication — critical in changeover setups

Potential for interlocking / safety features — to prevent simultaneous connection of both sources
