Thumbwheel Switches with External Stoppers:
A7BS-20[]-S(-1)
Use A7BS-S Stopper Pins to make dial display restrictions for these Switches.
Insert the Stopper Pins in the positions required to give the desired display range. For example, for a display range of 0 to 5, insert a Stopper Pin at position 1 (see following diagram) to stop the display from going above 5 when the (+) button is pressed, and insert a Stopper Pin at position 2 to stop the display from going below 0 when the (-) button is pressed.
Stopper Pins

1. Two pins constitute one set.
2. The first shipment is free and is attached to the Switch.
Order the A7BS-S separately if it is required for maintenance.
