By-pass of an electrical component

A modular by-pass device of an electrical component comprising:

• a housing comprising:
• a movable means of sealing;
• and
• a plurality of conducting terminals, each having an end connected to an electrical component circuit, and each having another end fastened to a wall of the housing and projecting into an interior of the housing to form a contact post,
• an actuator providing transposition between two positions of a control device comprising a plunger shaft and a spring arranged in a space formed between the plunger shaft and an internal wall of the housing,
• a trigger comprising:
• a retention device of the plunger shaft held in place by a fusible material, and
• an adapter held in a central bore of the plunger shaft, and
• a reversing switch comprising a contact zone providing electrical continuity between at least two of the contact posts of the terminals,
• wherein the plunger shaft of the actuator is a one-piece shaft equipped with a shoulder comprising an end with a cylindrical part in the form of a barrel comprising the central bore and a first seating providing replacement and fastening of the trigger, and
• wherein the adapter comprises a post carrying an ogival first pin supported by at least one tappet, the said at least one tappet fitted in a coil and held in a locked position by a retaining wire hooked on the fusible material.
