The invention discloses a push switch with an LED (light-emitting diode), which comprises a base, terminal plates, a sliding body, an elastic piece, conductive clamps, the LED, an upper cover and a clamping pin. A containing chamber is arranged below the base in a concave manner. Each terminal plate comprises a first terminal, a second terminal and a third terminal which are not in contact with each other. The two conductive clamps are respectively arranged at the two corresponding sides of the sliding body in a fixed manner, the base is covered by the upper cover, and the upper cover is provided with an opening which is correspondingly sheathed at the periphery of the sliding body. The sliding body can be selectively located at the first or second positions, so as to promote electrical connection between the third terminal and the second terminal or between the second terminal and the first terminal by the conductive clamp. Therefore, an LED terminal of the push switch is fixed in the base and cannot easily shed off; as the entire volume is small, the push switch can be applied in a light, thin and small electronic product.
