Abstract
A switch assembly is provided for mounting on a circuit board and for receiving a coax connector plug that opens the switch and connects the central coax plug element to one of the switch contacts, which enables the use of a plug (100) without a long projecting center contact element (102) and which enables many degrees of misalignment between the plug and switch. The switch (10) includes a housing (11) with an exposed upper face (22) having an entrance (24) for receiving the connector plug. First and second contacts (12, 14) are mounted on the housing, with the first contact including a resilient beam (18) biased up against the second contact but deflectable downwardly out of engagement with the second contact. An electrically conductive projection (19) projects upward at least partially through an opening (26) at the bottom entrance, so the center contact element of the plug does not have to project deeply through the opening in order to operate the switch and electrically connect to the beam. The entrance is tapered and has electrically conductive entrance walls. The outer element (106) of the connector plug preferably has a largely spherical front end, to make contact with the …
