Foot switch connector Euro. www.haraldswerk.de

Motivation

As a Shakuhachi player I need my hands on the flute. So I use me feet to manipulate parameters and switches on the synthesizer. This module was originally build for my Shakuhachi to Synth project with banana jacks and for 15V PSU to provide the possibility to connect foot switches with the synthesizer and keep the patch intact when they are removed. The signal is not routed through the foot switch. Instead CMOS switches are used, turned on and off with the foot switch. So the signal stays within the synthesizer and the connection to the foot switch carries only DC. Removing the foot switch does not interrupt the signal flow in the synthesizer.

Here is the same foot switch for the Euro rack format.

Specs and features

Four independent switches
Signal flow stays intact when foot switch removed
Runs on +/-12V and +/-15V
Power consumption below 10mA each rail

Implementation

Schematic

Description:

The switch in the DG202 is hold in on position with a 100k resistor against the positive rail. With a foot switch attached you can pull down the hold voltage when you close the foot switch.
