What type of keys on a teach pendant keypad are designed for a single specific function?

Hard keys on a teach pendant keypad are specifically designed for a single function, providing a dedicated and direct way for the operator to access critical commands or features without the need to navigate through menus. These keys are typically marked with symbols or labels that clearly indicate their purpose, ensuring that users can quickly and efficiently execute commands. This design increases operational efficiency, as operators can rely on tactile feedback and the immediacy of hard keys for tasks such as starting or stopping a robot, adjusting speed settings, or enabling safety locks.

In contrast, soft keys are often context-sensitive and can change their function based on the current screen or mode, while function keys may perform a range of programmable actions. Macro keys allow the execution of a series of commands but are not limited to a single, fixed function.
