I've modified your program so it should work. If press the button on
pin B7 down, the LED will go on. When you release the button, the LED
will go off.
Code:

#include <16F886.h>
#fuses INTRC_IO, NOWDT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)

#define SW_PIN   PIN_B7
#define LED_PIN  PIN_A1

#int_rb
void rb_isr(void)
{
int8 value;

output_toggle(LED_PIN);
delay_ms(10);

value = input(SW_PIN);
}

//============================
void main()
{
int8 temp;

output_low(LED_PIN);

temp = input(SW_PIN);
clear_interrupt(INT_RB);
enable_interrupts(INT_RB7);
enable_interrupts(GLOBAL);

while(1);
}

Thank you very much PCM programmer.
Now it is working perfectly.
I found myself that my understanding with 886 wasn't deep enough.

Thank you again.
