Millborn lt control switches, cam operated. Type m25 are built from uniform switching packets assembled from a stack. Each packet contains two sets of contacts. The moving contacts are operated by module cams, which are actuated by a spring-operated mechanism. These switches are supplied with bakelite ball handle and dial plate. Handle can be fixed in any desired direction. Switching capacity and mechanical life: these switches are capable for continuous duty filing as much as 200 switching operations per hour and mechanical life is exceptionally high running into millions of switching cycles. Contacts are made from silver cadmium oxide. Connections: the connection terminals are easily accessible. The terminal screws have only to be loosened, and the bare wire ends put under the arched washers and clamped tight.
