ABSTRACT:
A track switch for use with a track intersection for movable wall panels wherein the track intersection has a first track path and a second track path for the movable wall panels to traverse. The switch includes an actuator movable between a first actuator position and a second actuator position upon actuation by a power source. The switch also includes a diverter operatively connected to the actuator and selectively movable between a first diverter position defining the first track path and a second diverter position defining a second track path. Movement of the actuator between the first and second actuator positions causes the diverter to move between the first and second diverter positions, respectively. The actuator includes a biasing mechanism for biasing the diverter toward the selected diverter position. The biasing mechanism is operatively connected to the diverter such that, as the diverter is in or moving toward the selected diverter position, the biasing mechanism allows the diverter to move toward the non-selected diverter position upon application of a force against the diverter toward the non-selected diverter position.
