Key selector

• Purpose: The primary purpose of a key selector is to provide a secure and convenient way to operate an automatic gate, especially in situations where remote controls, keypads, or other access methods might not be practical or desired (e.g., for maintenance personnel, or as a backup).
• Mechanism: It typically consists of a sturdy, often metal, housing that is mounted on a wall, column, or recessed into a wall. Inside, there's a key cylinder that, when turned, activates a microswitch or set of contacts. These contacts then send a signal to the gate opener's control unit, telling it to perform a specific action (open, close, or a specific operating mode).
• Security: Key selectors are designed to be robust and weather-resistant, often with vandal-proof features. The use of a physical key adds a layer of security, as only individuals with the correct key can operate the gate.
• Types and Features:
  • Key-operated switches: The most common type, where inserting and turning a key triggers the gate's action.
  • Universal or European cylinder locks: Different types of key cylinders can be used for varying levels of security and compatibility.
  • Single or multiple microswitches: Some selectors have one switch for a simple open/close function, while others have multiple switches to allow for more complex operations (e.g., partial opening, full opening, lock, exit only, automatic mode).
  • Wall-mounted or flush-mounted: They can be installed on the surface of a wall or column, or recessed for a more discreet look.
  • Material: Often made from durable materials like aluminum or die-cast metal to withstand outdoor conditions and potential impact.
• Integration: Key selectors are accessories that integrate with the overall automated gate system, complementing other access control methods like remote controls, keypads, transponder readers, or even smartphone apps.
