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 stoppers are also available. Add -S after the 203, 206, 207, 219, 254, or 255 in the model number and specify the display range in the . For example, to specify the range 0 to 6, add -S06 to the model number (e.g., A7PS-206-S06-1). -SOF can not be available for type -254, -255. 4. Models with +, - displays can also be produced. Add -PM after the 206 in the model number (e.g., A7PS-206-PM or A7PS-206-PM-1) *1. Models with diodes are available. Add -D to the model number (e.g., A7PS-207-D or A7PS-207-D-1). End Caps Accessories (Order Separately) Use accessories, such as End Caps and Spacers, with the Switch End Caps are used on the Switch Units at each end and allow all the Units. Switch Units to be securely mounted to a panel. They come in pairs, one for the left and one for the right.
