Thumbwheel Switch
A7BS/A7BL
Wide Range of Locking-type
Models Available
• Character height of 4.8 or 3.2 mm makes for easy-to-
view display.
• Installation is easy with snap-in mounting.
• The series includes a complete range of locking-type
models that prevent accidental operation.
Ordering Information
Switches (Single Switch Units)
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 Switch Units.
3. Models with +, - displays can also be produced. Add “-PM” after the “206” or “207” in the model number (e.g., A7BS-206-PM or A7BS-207-PM-1).
*1. For models with PCB terminals, add “-P2” to the model number (e.g., A7BS-
207-P2-1).
*2. Models with internal stoppers are also available. Add “-S@@” after the “206”
or “207” 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.,
A7BS-206-S06-1).
For structural reasons, models with stoppers cannot be manufactured for
the A7BS-254 and A7BS-255.
*3. Models with diodes are available. Add “-D” to the model number (e.g., A7BS-
207-D or A7BS-207-D-1).
