Abstract
The magnetic trip comprises a yoke, a trip device, a stationary contact and a switching electrode. The yoke (1) is formed by cutting out and bending a metal strip so as to incorporate a connection terminal (2) and permit the fixing in position of the induction coil (6) by soldering one of its two ends to the yoke (1), the other end being soldered to the stationary contact (5) which is carried by the yoke (1), but is insulated in relation to the latter. <IMAGE>
