Switches Notes about component heights, swapping rotary and toggle switches available from Tayda, per their datasheet, appear to differ in height by 1.65 mm. The 3PDT I used appears to be larger than the SPDT switch, needed a nut behind the panel on the circumference of the main (cylindrical or conical) knob shape, without the two keybeds in storage; decipher key matrix, work out either MC or dumb resistor array to output correct volts for each key.
