SDFileSystem - can't use card detection

Hi guys!

My board is Nucleo STM32F411. I'm trying to init SDFileSystem like this:

My code

#include "mbed.h"
#include "SDFileSystem.h"

Timer timer;
DigitalIn button(USER_BUTTON, PullUp);
DigitalOut led1(LED1);
SDFileSystem sd(SPI_MOSI, SPI_MISO, SPI_SCK, SPI_CS, "sd", PC_10,  SWITCH_NEG_NC, 1000000);
char buffer[4096];

// rest of the code
// ...

It seems to be correct but compiler returns this message:

Error

Error: Identifier "SWITCH_NEG_NC" is undefined in "main.cpp", Line: 7, Col: 69

What can be wrong?
