Rotary Code Switches body (1 switch unit)
Note 1. The classification diagram shows a combination of four switch units and an optional mounting plate to create a four-digit number.
Note 2. The above model is for one switch unit.
Note 3. Dial "+" and "-" indications are also available. Add "-PM" after "-206" or "-207" in each model.
Example: A7BS-206-PM, A7BS-207-PM-1
*1. For PCB terminals, add "-P2" after the model number. (Example: A7BS-207-P2-1)
*2. Models with internal stoppers are also available. Add "-S□□" after "206" or "207" in the model number and specify the operating range in □□. For example, if the range is 0 to 6, then use "-S06". (Example: A7BS-206-S06-1) Due totheir structure, -254 and -255 types cannot be manufactured with stoppers.
*3. Diode types are also available. Add "-D" after the model number. (Example: A7BS-207-D, A7BS-207-D-1)
