IEC selector-switch contact: 2 position normally open return from right
Selector-switch contact form: 2 Position Normally Open Return From Right.
In plain English
What does IEC selector-switch contact: 2 position normally open return from right mean?
A rotary selector has discrete handle positions and one or more contact blocks driven by its mechanism. A contact shown as normally open or normally closed describes the stated reference position; it does not give the whole switching table across the remaining positions. This entry identifies the 2 position normally open return from right form in the publisher's IEC-context family.
A simple example
For a local/off/remote selector, prepare a contact-versus-position chart alongside the schematic. The chart tells the installer which input is active at each handle setting, while spring-return, maintained and key-operated marks explain how the operator reaches or leaves that setting. The normally-open designation starts with a non-conducting output or open contact in the documented reference condition; operation changes that state. The return arrow applies to the right operating position. Other positions need their own return or maintained-state description.
What the drawings help you do
A vendor neutral-position number must be read with that vendor form and the project legend. It does not automatically establish a key-removal position, a contact overlap or an off state. Those details need their own table or equipment reference.

How to read it
- The normally-open designation starts with a non-conducting output or open contact in the documented reference condition; operation changes that state.
- The return arrow applies to the right operating position. Other positions need their own return or maintained-state description.
- A vendor neutral-position number must be read with that vendor form and the project legend. It does not automatically establish a key-removal position, a contact overlap or an off state. Those details need their own table or equipment reference.
Information to show or reference
- Label every handle position and preserve its reference orientation.
- Cross-reference a contact-versus-position chart.
- State maintained positions, return directions and any key-removal conditions.
A distinction that matters
This entry adds the 2 position normally open return from right detail to the broader selector-switch contact family. A vendor neutral-position number must be read with that vendor form and the project legend. It does not automatically establish a key-removal position, a contact overlap or an off state. Those details need their own table or equipment reference.
