Keyed push buttons restrict access to specific controls or processes by only changing states when the correct key unlocks the button. They have large, mushroom-shaped heads that are intuitive and easy to actuate when wearing gloves, making them ideal for use as emergency stop (e-stop) buttons. Non-illuminated push buttons don't have any lighting elements and are suitable for situations where a light indication is unnecessary or could be distracting.

These miniature push buttons fit into tight or confined spaces on panels where larger push buttons will not fit. Their small footprints allow them to fit on smaller panels or when positioning multiple buttons in a compact space. They have extended bodies to help users engage them and make them stand out.
