Abstract
An assembly includes an electrical switch and an elastically deformable control blade for controlling change of state of its trip member. The control blade comprises: (i) a fixing branch; (ii) an actuation branch which, in the absence of application of an actuation effort, stresses the trip member in the direction of closure of the electrical switch, and (iii) a control branch which can pivot about an axis to provoke tilting of the actuation branch against its elasticity to keep the electrical switch in an open free state. The assembly may include a locking device for locking the control blade in an initial position of delivery of the assembly. The unlocking of the control blade may be provoked automatically upon a first application of an actuation effort on the control blade.
