Programmable Tap Tempo Switch ONE TAP is a Tap Tempo Foot Switch which provides ultimate programming flexibility by the use of dip switches, which can be accessed by removing one side panel. The output can be programmed as: > Normally Closed or Normally Open. > Switch contact between Sleeve & Tip, Sleeve & Ring, or Sleeve & Tip + Ring. > Engage a 4.7kΩ pull-up resistor between Sleeve & Tip or Sleeve & Ring. > An LED is provided for applications where the Foot Switch is used to latch a device ON, and that device provides power for the LED. For most Tap Tempo applications, the LEDs will not light up.
