Button is always low?

//ESP32

const int switchStartStopPin = 25;

typedef enum SWITCH
{
  SWITCH_NONE,
  SWITCH_1,
  SWITCH_2
} switch_t;

switch_t readSwitch(void)
{
  int switchAdcValue = 0;
  // Switch connected directly to individual separate pins
  if (digitalRead(switchStartStopPin) == LOW) return SWITCH_1;
  Serial.println("Switch 1 pressed");
  if (digitalRead(switchLfPbPin) == LOW) return SWITCH_2;

  return SWITCH_NONE;
}

What am I missing?

2

The code tags that I added for you?...
The schema of how things are wired and powered?
The rest of the code?

3

The rest of your code.
A clear description of your problem.
A schematic

Are just three of the things that come to mind

5

how is it wired? as you don't set the pins, they are just INPUT. do you have an external pull-up or pull-down resistor?
