Example
Use of the operating mode switch with 3 switch positions.
Actuating a key switch allows the operating mode change.
The actual change is implemented with an acceptance
button.
The connections are implemented as follows:
• Operating mode switch S1 at device terminals IS1 to IS3.
• Key switch S2 at device terminal IS6.
• Acceptance button S3 at device terminal IS8.
This looks as follows in the electrical circuit diagram:
