Pyrotechnic switch with a fuse element

A pyrotechnic switch comprising:

• at least a first circuit portion with two connection terminals, arranged to be part of an electrical circuit;
• a mobile body, arranged to pass from a first position to a second position, and thereby cause the first circuit portion to open;
• a pyrotechnic actuator, arranged to control the movement of the mobile body from the first to the second position;
• and
• at least one fuse element arranged to interrupt an electrical current flowing between the connection terminals of the first circuit portion, wherein the at least one fuse element is isolated from at least one of the two connection terminals of the first circuit portion when the mobile body is in the first position, wherein the mobile body is configured to electrically connect the at least one fuse element with at least one of the two connection terminals as a result of movement of the mobile body between the first position and the second position such that when the mobile body is in the second position, an electric arc electrically connects the at least one fuse element with at least one of the two connection terminals.
