What function does a latched controller serve?

A latched controller is designed to toggle the state of an output with each activation, meaning it operates in a switch-like fashion. When you press the button, the controller activates the motor or device, and on the second press, it deactivates the motor or device.

This functionality is particularly useful in assistive technology environments, where a user may have limited mobility or dexterity. The ability to control a device with a simple press—turning it on with one press and off with another—enhances usability and independence.

While other functionalities, such as speed control for a motor, seat adjustment, or light activation, can certainly be found in various assistive devices, they do not specifically describe the latched operation mechanism. The essence of a latched controller lies in its ability to maintain the current state until prompted to change by another input, delivering a straightforward and effective user experience.
