Swing Turnstiles are a type of access control gate used to regulate entry 

and exit in various settings such as office buildings, public transportation stations, 

and sports arenas. Unlike traditional turnstiles that use rotating arms, swing turnstiles feature barrier arms 

or panels that swing open and closed to allow or restrict passage.

Here are some key features and aspects of swing turnstiles:

1. Design: 

They typically have one or two swinging barriers made of glass, metal, or plastic. 

These barriers swing open to allow entry and close to block passage.

2. Operation: 

Swing turnstiles can be operated manually, semi-automatically, or fully automatically, 

often integrating with access control systems like keycards, biometrics, or ticket readers.

3. Accessibility: 

They are designed to provide wider passages compared to traditional tripod turnstiles, 

making them suitable for people with disabilities, those carrying large items, or for wheelchair access.

4. Security: 

Swing turnstiles can be equipped with sensors and alarms to prevent unauthorized entry 

and ensure that only one person passes through per authorized access.

5. Usage: 

They are commonly used in places where aesthetics and accessibility are important, 

such as corporate offices, airports, and high-end facilities.

Overall, swing turnstiles offer a modern, secure,and accessible solution for controlling pedestrian traffic in a variety of environments.
