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 casing 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.
