The Key Press (Push-Button) Attenuator is a distinct product category. Unlike rotary knob versions, these are valued for speed and visual confirmation. Engineers use them in production lines and high-speed R&D because you can "set" the dB value instantly by toggling switches rather than turning a dial.
