What type of switch installation is designed to prevent accidental activation?

Guarded switches are specifically designed to prevent accidental activation through their physical configuration. These switches feature protective enclosures or barriers that require intentional action to reach and toggle them. Such design minimizes the risk of unintended operation, which is particularly important in aircraft systems where safety and reliability are paramount.

In contrast, other types of switches may not provide this level of protection. Standard toggle switches are easily accessible and can be activated without any additional effort, which increases the risk of accidental actuation. Momentary contact switches are meant to be pressed only briefly to perform their function, but they may be vulnerable to unintentional engagement if not properly shielded. Manual reset switches, while they do require a deliberate action to reset after activation, do not provide the same protective barrier against accidental operation as guarded switches do. Therefore, guarded switches are the most effective option for preventing accidental activation in sensitive applications.
