The invention discloses an elevator switch controller capable of automatically shutting down elevator some time after fire occurs. The elevator switch controller comprises a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a sixth capacitor, a seventh capacitor, a first audion, a second audion, a third audion, a fourth audion, a fifth audion, a first diode, a second diode, a third diode, a first voltage-stabilizing diode, a second voltage-stabilizing diode, a first relay, a second relay, a field-effect transistor, a thyristor, a potentiometer, a power source and an ion type smoke sensor. According to the invention, when detecting a fire smoke signal, the ion type smoke sensor outputs a voltage enabling the field-effect transistor to be turned on; when it gets smoky to a certain degree, the first voltage-stabilizing diode triggers the thyristor for enabling the first relay to be electrified; the first relay gets closed and a voltage is loaded on the fifth audion; the base voltage of the fifth audion is gradually increased to control the fifth audion to be turned on; when the output voltage of the fifth audion enables the third diode to be turned on, the second relay is controlled to act, and therefore the power of an elevator will be automatically cut off within a period after the fire occurs.
