An adaptation accessory 10 is intended to be inserted between a differential switch and electrical accessories, especially an MX or MN circuit breaker, and a CAOF or SD changeover switch. The mechanism 46 includes a rotary mechanism plate 48 with a disengagement lever 56, two mechanical links 34, 36 for disengaging in opposite directions with the differential switch, and a signalling switch 70 controlled by the mechanism plate 48. A cam 82 of the mechanism plate 48 interacts with a pawl 84 for driving a latch 86 having a pin 90 integral with the second mechanical link 36. The first link 34 derives, from the disengagement movement of the differential switch, a movement for pivoting the disengagement lever 36 towards the disengaged position. <IMAGE>
