What is a health switch used for on vending machines?

A health switch on vending machines serves as a temperature switch, which plays a crucial role in maintaining food safety. This switch is responsible for monitoring the internal environment of the machine, particularly the temperature of perishable products. If the temperature rises above a certain threshold—indicating that the items may be unsafe for consumption—the health switch can trigger an alert or disable the machine to prevent any potentially harmful food from being sold.

This helps ensure compliance with health regulations and protects consumers from purchasing spoiled products. The functionality of the health switch makes it integral to the operational integrity of vending machines that dispense temperature-sensitive items.
