The invention relates to an emergency switch that includes a body receiving a mobile member capable of translation and capable, under the effect of an axial pressure through a mushroom member, of moving from an extended position into a retracted position. Each of the positions are indexed by a blocking device capable of interaction with an extended position notch and with a retracted position notch, the position change being managed by a guide. The body fixedly includes, in the inside thereof, a concentric bushing in which the mobile member is capable of axially moving and which includes a portion of the guide while the mobile member includes the other portion. The blocking device is made in the shape of a piece of material flexibly and elastically attached to the rest of the bushing via a blade.
