A rail switch (1), particularly for an overhead conveyor system, adapted to assume at least two switch positions (I, II, III) for selectively connecting a first rail (2) comprising a runway (2a, 2b) for casters (7a, 7b) of conveyor carriages (6) to the free ends of other rails (3, 4, 5).

A rail switch (1), particularly for an overhead conveyor system, adapted to assume at least two switch positions (I, II, III) for selectively connecting a first rail (2) comprising a runway (2a, 2b) for casters (7a, 7b) of conveyor carriages (6) to the free ends of other rails (3, 4, 5). The switch includes a switch portion (10) carrying a corresponding runway (10a, 10b) and having one of its ends connected to the free end of the first rail (2) by a hinge (9) permitting it to be pivoted about a pivot axis (11) so that the opposite free end of the switch portion (10) may be selectively connected to the free ends of the other rails (3, 4, 5). To ensure substantially smooth passage of the casters (7a, 7b) over the hinge (9), the runway adjacent the hinge (9) is formed by mutually overlapping runway surface portions (17a, 17b, 19a, 19b) on the switch portion (10) and on the first rail (2).

A rail switch for connecting a free end of a first rail to free ends of at least two other similarly shaped rails, each of said rails having a centerline and a runway formed of two angularly inclined runway surfaces on either side of the centerline which are adapted to carry a pair of similarly angularly inclined casters of a conveyor carriage, said rail switch comprising a switch portion having a corresponding runway connected at one end to the free end of said first rail by a hinge means that permits said switch portion to pivot about an axis located on the centerline of aid first rail for selective connection of an end opposite said one end to the free ends of said other rails, at least a portion of the runway surfaces of the switch portion at said one end adjacent said hinge means overlapping a portion of the runway surfaces of the free end of said first rail and at least a part of said overlapped portion of the runway surfaces of the first rail being inclined inwardly at an angle a
