The invention provides a manufacturing method of a gamepad membrane switch. The manufacturing method of the gamepad membrane switch includes the following steps that a, a digital signal key and an analog signal key are set; b, the bottom of the digital signal key is set as a first substrate, a first conductive metal circuit is printed on the first substrate, a low-resistance carbon layer is printed on the first conductive metal circuit, and an insulation groove is formed; c, first conductive silica gel is arranged over the insulation groove; d, the bottom of the analog signal key is set as a second substrate, a second conductive metal circuit is printed on the second substrate, and a high-resistance carbon layer is printed on the second conductive metal circuit; e, second conductive silica gel is arranged at the upper portion of the center of the high-resistance carbon layer, and the bottom face of the second conductive silica gel is a curved surface. The manufacturing method is simple in manufacturing technology and low in manufacturing cost, the short-circuit problem can be remarkably solved, the high anti-corrosion effect is achieved, the service life of the membrane switch is long, and a user can achieve different operations by inching the switch.
