A slat sorter having a series of platens slidably mounted on an array of slats driven by an endless chain with each platen having a diverter pin for enabling it to be diverted between a straight-through track and at least one divert track. A switch having an elongated arm having a pivot end and a tip opposite and upstream the pivot end which is urged by a prime mover, that preferably is a limited angle torque electric motor, between a straight-through position directing a diverter pin to travel along the straight-through track and a divert position directing the diverter pin to travel along the divert track. The arm has a cutout which allows the arm to be urged from one position to the another position before the diverter pin is completely downstream and cleared of the arm. Operably associated with the arm is a brake for enabling the arm to be urged toward either the straight-through or divert position by an oncoming divert pin to prevent the divert pin from colliding head-on with the arm. Each slat is adjacent a wheel-like bearing on a track of the sorter with the bearing being attached to a boss extending outwardly from the slat. The boss is part of a bushing pressed into the end of the slat which accepts a ball detent pin that can be withdrawn from the bushing and boss to permit removal of the slat.
