Thumbwheel Switch A7D/A7DP CSM A7D A7DP DS E 6 2 Ultra-small, Low-cost, Push-operated Switches All-in-one design means fewer parts are required. This product delivers high reliability at a low cost. Uses long-lasting resin springs to achieve a long mechanical durability expectancy of 30,000 operations. Models with stoppers for restricting the setting range are available. The series includes a complete range of pen-push models that prevent accidental operation.

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 106 or 206 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., A7D-106-S06-1). 4. Models with +, - displays are also available. Add -PM after the 106 or 206 in the model number (e.g., A7D-106-PM or A7D-106-PM-1). Accessories (Order Separately) Use accessories, such as End Caps and Spacers, with the Switch Units.

End Caps End Caps are used on the Switch Units at each end and allow all the Switch Units to be securely mounted to a panel. They come in pairs, one for the left and one for the right. Spacers Spacers are used for creating extra space or gaps between the Switch Units and have the same dimensions as the Switch Units themselves. There are also Spacers with engraved characters or symbols that can be used for indicating units, such as time and length. (Refer to the following table.)
