What is one common application of pushbutton interlocks?

Pushbutton interlocks are commonly used to ensure safe operation in scenarios where multiple motor starters interact with one another. When interlocking two motor starters, pushbutton interlocks allow operators to control which motor can be activated at a given time, preventing simultaneous operation of motors that might be detrimental to the system. For example, if one motor is running while another is attempting to start, it could lead to mechanical conflicts or overloads. The interlocking mechanism effectively safeguards against such issues by making sure that only one motor can be active based on the operator's input.

This application is critical in various industrial settings where safety and equipment integrity are paramount. It ensures that operational procedures follow safety protocols, thereby reducing risks of accidents or machinery damage. By using pushbutton interlocks in this manner, operators can maintain better control over complex motor systems while adhering to safety regulations.
