Sobre este producto
  • This key module is equipped with four independent four-pin key switches, featuring a metal dome structure design for excellent mechanical protection performance.
  • The four-pin keys adopt a momentary contact design: the circuit conducts when pressure is applied (button pressed) and automatically disconnects when the pressure is released.
  • The analog switch toggles the output state based on the input analog value, typically featuring multiple input channels and one output channel, and is compatible with Arduino.
  • Four buttons share the same analog output port. Each button outputs a distinct characteristic voltage when pressed, allowing the system to accurately identify the specific pressed key by detecting this analog signal.
  • The four-bit analog key module has four momentary push buttons, with all key signals output through a single analog interface.
