Since the bus bar electrification is mounted so compactly and close in on the tongue of the switch, only a slight additional switch throw is required for clearance of trolley collectors.

Both the Three-Way and the Wye type electrified tongue switches are assembled on the same frame. On the Wye switch the center hanger is replaced by a permanent guard in order to prevent trolleys from leaving the tongue if stopped at this position.

All open ends are safely guarded against trolleys leaving the track at switch connections.
