Abstract

A pressure sensor for detecting an electric arc in an electrical switchboard, the sensor being in an enclosed case containing a conical opening, the case being placed in the switchboard. A pressure switch in the sensor is attached to the interior of the case and is electrically connected to a circuit board for transmitting a signal when a contact in the pressure switch is closed. When a pressure wave created by the electric arc enters the case through the conical opening it forces a contact on the pressure switch to close thereby completing a circuit with the circuit board which transmits the signal to, for example, a central processor, to turn off the source of electricity thereby quenching the electric arc.
