Toggle switches are actuated by moving a lever back and forth to open or close an electrical circuit. There are two basic types: maintained contact and momentary contact. Maintained contact toggle switches maintain the position to which they are moved or actuated. Momentary contact toggle switches do not.
A junction box is an electrical enclosure that houses one or more wiring connections. The box protects the connections, which usually contain vulnerable points such as wire splices, from environmental conditions and accidental contact.
Junction station usually refers to a railway station situated on or close to a junction where lines to several destinations diverge. The usual minimum is three incoming lines. At a station with platforms running from left to right, the minimum to qualify as a junction station would usually be one line on the left and two on the right (or vice versa).
