The present disclosure relates to a linked crank mounting device for use with a switch rail, comprising: an input terminal or series of input terminals; an actuator; an output connector; and attachment means for rigidly attaching the linked crank mounting device relative to the railway; wherein the input terminal or terminals are for receiving input power, the output connector is directly or indirectly mechanically linked to at least one of a switch rail or an output connector of a further linked crank mounting device, and the actuator applies the input power to the output connector.

A spring-set, electromagnetically released brake that requires a relatively small amount of current to release is provided. The brake includes a magnet shell disposed about a first axis. The shell includes a radially outwardly extending pole. The brake also includes an armature disposed radially outwardly of the pole and pivotable at a first axial end and a first engagement element, such as a brake shoe, coupled to the armature proximate a second axial end of the armature. The brake further includes a spring disposed about the pole. The spring biases the armature radially outwardly to urge the first engagement element towards a second engagement element such as a friction surface in a brake drum. Finally, the brake includes a coil disposed about the pole and means for selectively energizing the coil to urge the armature radially inwardly and the first engagement element away from the second engagement element. A bobbin for use in the brake is also provided. The bobbin includes a substantially cylindrical body portion disposed about a second axis and first and second discs extending radially outwardly from first and second ends, respectively, of the body portion. The bobbin further includes a flange extending radially inwardly relative to the second axis and a projection extending axially relative to the second axis. The flange and projection are configured to engage the magnet shell and prevent radial and axial movement of the bobbin and coil.
