*1 The auto switches with improved water resistance can be mounted on the above models, but the water-resistance of the model cannot be guaranteed. Check with the manufacturer regarding water-resistant types for the above model numbers.
*2 The 1‑m type lead wire is only applicable to the D-A93.
*Solid state auto switches marked with 〇 are made upon receipt of order.

**The D-P4DW type supports ø40 to 63 (diameter 40 to 63 mm).
**Only the D-P4DW type is assembled at the time of shipment.
***The D-P3DWA□ type supports ø25 to 63 (diameter 25 to 63 mm).

*Aside from those models listed above, there are other applicable auto switches.
*Auto switches are shipped together (but not assembled).
