1P6T rotary switch

This is the 6-position rotary switch as sold by Small Bear and other online stompbox parts vendors.

There are two sets on connecting pins; the front set of 5 which are closest to the shaft, and the back set of 5, shown at the bottom in this photo.

The R1 and R2 pins are the rotor connections which are the common outputs for that row of pins. On the raw switch, the front and back rows are not electrically connected to each other. Each rotor connects in sequence to its set of 4 pins but the ordering is somewhat strange. The shaft (and knob) will rotate to 6 positions.

In position 1, the R2 rotor connects to pin 1 and the R1 rotor is not connected to any pin.

In position 2, the R2 rotor connects to pin 2 and the R1 rotor is not connected to any pin.

In position 3, the R2 rotor connects to pin 3 and the R1 rotor will connect to the pin on its left labeled with a small 3. Front and back rows are still not connected.

In position 4, the R2 rotor connects to pin 4 and the R1 rotor will connect to the pin to the right of #5 which is labeled with a small 4.

In position 5, the R2 rotor is not connected to any pins and the R1 rotor will connect to pin 5.

In position 6, the R2 rotor is not connected to any pins and the R1 rotor will connect to pin 6.

Note that even though both rows of pins have position 3 and 4 labeled pins, the two rows of pins do not make contact with each other when in those positions. R2 connects to its pin 3 and R1 connects to its own pin 3 but none of the pins from the back row and front row are connected. The same logic applies to position 4.

In typical stompbox use, such as for selecting 6 capacitors in a circuit, the R1 and R2 pins will be wired together, either with a jumper or on the pcb. When this is done, R1 and R2 become a common connection that is routed to the 6 output pins; usually the ones labeled with the larger numbers 1 through 6. For example, as an input capacitor selector, the signal input would be routed to both R1 and R2. One end of each of the 6 capacitors would be connected to a pin labeled 1 though 6 with one capacitor per pin. The remaining ends of the capacitors would be tied together and wired to the circuit input.

In this configuration, the rotary switch selects one capacitor for the signal to be sent though to the circuit. By using different values for each of the 6 capacitors, you have 6 tone variations.

I hope this makes the use of the 1P6T rotary switch easier for you.
