Note: 1. The classification diagrams show 4 Switch Units combined with End Caps to create 4-digit displays. 2. The model numbers given above are for 1 Switch Unit. 3. Models with +, displays can also be produced. Add -PM after the 106 or 206 in the model number (e.g., A7MA-106-PM or A7MA- 106-PM-1). 4. Equipped with built-in diode. 5. Models with diodes are available. Add -D to the model number (e.g., A7MA-207-D or A7MA-207-D-1). Accessories (Order Separately) Use accessories, such as End Caps and Spacers, with the Switch Units.
