for() loop breaks when using the OR operator (C)

As a beginner, I have been typing away when I noticed OR (in C ||) broke the for loop. Here is the code:

#include <stdio.h>

int main() {
    
    char ch;
    
    printf("Typing program...\n");
    printf("Type away:");
    for(;;) {
        
        ch = getchar();
        if(ch == '~' || '`') {
            
            break;
            
        }
    }
    return(0);
}

When compiled the code doesn't seem to return any errors, but the for loop breaks when I paste the right side of the OR operator. What could cause this? Code is from C for Dummies, while I was doing an "exercise". Everything that I tried else would result in an error.
