Abstract
The invention provides a micro pressure controller which comprises a micro switch, a cover body, a connector, a spring seat, a spring, and a sleeve structure. The spring is disposed at the inner side of the sleeve structure, and the two ends of the spring along a first direction are connected with the spring seat and the sleeve structure respectively. The position of the spring seat along the first direction can be adjusted by a threaded component arranged through the cover body, so as to compress or stretch the spring. The set value of the micro pressure controller is determined by the degree to which the spring is compressed or stretched. The connector is connected with a to-be-tested object, and does slight motion. When the pressure exceeds the set value, the connector drives the sleeve structure to move against the acting force of the spring so the sleeve structure can trigger the micro switch.
