Abstract: The invention comprises an electrical connector having a housing. The housing has a top, a front, a back, and a contact receiving cavity extending from the back to the front of the housing and being open along the top. A guide rail extends along a top portion of the contact receiving cavity. A contact is disposed within the contact receiving cavity and has a contact section which is accessible from the top of the connector. A grounding member is disposed around the housing and has a connection section for making ground connection with a matable connector and has a mounting section for mounting the connector. The guide rail guides the matable contact into correct position for proper mating with the contact.

Abstract: A random number selector is disclosed having a body generally in the form of a plate having three axially extending vertically spaced rectangular chambers formed in it. The three chambers are spaced from one another by a top generally rectangular part, two spaced intermediate parts and a bottom rectangular part, third rectangular parts extending from one side to the other. End parts closing the three chambers. The top of each rectangular part forming a shelf having half cylindrical shaped recesses. The recesses are adjacent one another so that the half cylindrical parts each engage the adjacent part so that the edge of each chamber has a sharp top edge. A transparent cover is supported over the front of the body and six red balls are received in the top chamber, four yellow balls in the intermediate chamber and three green balls in the lower chamber. A wedge shaped bead overlies the recesses and prevents the balls from rolling out when the selector is tilted back.
