Which type of keypad typically draws more current?

Touch screen keypads typically draw more current than other types of keypads because they require a display that is continually powered to show information and respond to touch inputs. This added functionality involves more complex electronic components and usually necessitates a backlight or a high-resolution screen, which significantly increases power consumption compared to simpler keypads like numeric or standard keypads that primarily function as input devices without a display.

In contrast, numeric, standard, and wireless keypads often utilize basic electrical components focused solely on input without the overhead of visual displays, keeping their current draw much lower. This difference in design and functionality is pivotal in understanding why touch screen keypads are associated with higher energy requirements.
