PURPOSE: A detector for an insulated charging pressure is provided to prevent electric shock through insulating a portion inserted to an operation space of an operation space terminal, and to adjust location of an alarming terminal according to pressure to be detected. CONSTITUTION: An end of an operation space (1) is bent for inserting an operation space terminal (2). A portion of the operation space terminal to be inserted to the end of the operation arm is insulated by an insulating material (4). Then, the insulated portion is inserted to an inserting groove. Herein, The portion is insulated not to flow current to the operation arm for preventing electric shock of a person. In a charged state of a fire extinguisher, the operation space terminal and an alarming terminal (3) are opened for an alarming apparatus not to generate alarming sound. By reduced pressure in the fire extinguisher, the operation space is shrunk for moving the operation space terminal. Thus, the terminal is short from the alarming terminal. Then, the alarming apparatus forms a closed circuit for generating the alarming sound. Then, an alarming terminal adjusting nut (6) is rotated to adjust location of the alarming terminal.
