ABSTRACT:
In a probe point device for electrical tests the metallic point proper is carried by a hollow insulating handle or push member on which an insulating head is slidably mounted, spring and abutment means normally maintaining the head at a position of rest at which it wholly covers the point. A fuse cartridge is disposed within the push member to connect the point with the flexible cable provided at the rear of the said member. This cartridge has at its front end an axial indicator button which, when the cartridge blows, acts on a pivoted pawl to engage a first nose thereof into an inner circular groove provided in the head, thus locking the push member with respect to the head at the position of rest. A second tooth of the pivoted point member also locks the push member with respect to the head if the cartridge is missing.
