Which component disables the entire launch control system when removed?

The arming switch with a removable key is designed to be a critical safety feature in rocketry systems. By requiring a removable key, it ensures that only authorized personnel can enable the launch control system. When the key is removed, the arming switch becomes inactive, effectively disabling the entire launch control system. This feature adds an essential layer of safety, preventing unauthorized or accidental launches.

In contrast, the ignition switch typically serves to initiate the ignition sequence once the system is armed, and the safety pin, while crucial for preventing accidental firing, usually relates to the launch mechanism itself rather than the entire system's activation. The launch button is merely the final trigger for an active system and does not disable the control system when removed. Therefore, the arming switch with the removable key plays a vital role in ensuring that the launch control system can be securely disabled.
