What function does a tamper switch serve in equipment?

A tamper switch is specifically designed to detect unauthorized access or tampering with equipment, making it crucial for maintaining security and operational integrity. This type of switch is typically triggered when someone attempts to open or interfere with the equipment, signaling that an unauthorized action has occurred. It plays an essential role in protecting sensitive components and ensuring that operational safety standards are upheld.

This function is particularly important in settings where equipment might be at risk of tampering, such as in commercial installations, to prevent theft or vandalism. Unlike the other options, which focus on regulating temperature, monitoring pressure, or measuring humidity, the tamper switch is solely focused on security, thus highlighting its unique role in equipment safeguarding.
