Abstract
An apparatus for connecting a testing electrode to a source of electrical energy having a housing for receiving a testing electrode and a member for connecting the testing electrode to a source of electrical energy. The invention is particularly characterized by contact means disposed about a common line, which face each other, and which are spaced apart by spring means, the arrangement being such that contact between the contact means of said housing and the contact means of said member can be effected by relative displacement of said housing and said member in the direction of said common line or by relative tilting of said housing and said member in any direction.
