A inflatable product for an inflatable body includes a casing with an airway adapted to communicate with an interior of the inflatable body, and a resilient element movably positioned inside the casing to define with the easing a space therebetween. An on/off switch is adapted to connect to an air pump. A driving element is movably positioned inside the casing to be in response to the movement of the resilient element so as to selectively activate the on/off switch to activate the air pump. A recoil element is positioned around the driving element and has a distal end which is abutted against the resilient element. The spring is compressed/decompressed when the resilient element moves in response to pressure inside the inflatable body so that activation/deactivation of the on/off switch is controlled via the movement of the resilient element as well as the compression of the spring.
