In my project I would like to switch between different resistors/capacitors on the fly, preferably without having to open the containing box around the PCB. Therefore, one idea was to use a jumper (connected via cables) which is placed on top of the box, which then can be used to set the currently active resistor/capacitor.
Are there other alternatives? I would prefer THT approaches, if possible.
The main aim of the circuit is to provide different R/C-constants for an OpAmp, operating at frequencies below 10 kHz. Switching between the different values should be as simple as possible, but still reliable, thus I prefer to avoid options mentioned like the alligator clips. Resistor values will be around 10k-10M, with voltages at +- 15V and currents < 1A. Cap values will be in the range of nF.
