Abstract: An electrical device and electrical compressor. The electrical device (102) comprises an electrical circuit (104) comprising a metal substrate (202), a layer of dielectric material (206) extending over the metal substrate (202), and a metal strip (208) extending over the layer of dielectric material (206). It further comprises a linking conductive part (218) intended to be connected to an electrical ground (106) and having a first contact end (220) intended to be pressed against the metal strip (208), and a pushing device (224) intended to take a first position, called the closed position, in which the pushing device (224) presses against a support portion (226) of the linking conductive part (218) so as to press the first contact end (220) against the metal strip (208), the support portion (226) being located away from the first contact end (220), and a second position, called the open position, in which the pushing device (224) allows the first contact end (220) to be separated from the metal strip (208).
