Switch Diverts is a complete integral unit that includes stub rails, curve bends and safety stop which is ready to bolt into track system. It is a welded system made entirely of steel. A patented feature provides positive actuation of the double lift accomplished through steel gears. It eliminated the difficulty in assembly and installation of conventional slide and lift arrangements. The advantage of switch is the ease and simplicity with which it may be installed. It is used in precision machine and laser cut parts. It provides the stronger design features that include rails, bridge assemblies and gates.

Switch Guard Rails is used to adjacent the switch point of a railway switch. It is comprised of a plurality of support chairs and an adjustable guard rail. It includes a surface for engaging and laterally urging the wheels of rolling stock in a direction toward the centerline of the track work and disclosed apparatus used for laterally adjusting and fastening the wheel engaging surface. It has guard or deflector rail positioned to prevent flanges of railroad wheels from striking the switch point. The guard rail is carried on support members for rigid retention in a fixed, predetermined position relative to the track. It provides a switch which stops a trolley from falling. These switches are constructed to exacting standards, template punched to ensure uniform component sizing and dimensions. It includes automatic or gear operated switches, mill, painted, galvanized and stainless steel finish.

Switch heater controls ensure that electric switch heaters operate the switches open during snow, sleet or ice weather. The controls are dispatcher operated or equipped for automatic operation with rails snow detectors. It also incorporates rail temperature limit controls to reduce power consumption. Each panel is a complete, pre-wired and tested package designed for easy installation and servicing. Controls are available for any make of tubular or flat electric switch heater, AC or DC voltages.

Switch mode power supply is an electronic power supply unit, which incorporates a switching regulator. This regulator is an internal control circuit that switches power transistors rapidly on and off in order to stabilize the output voltage or current. This regulator is used as replacement for the linear regulator when higher efficiency, smaller size or lighter weight are required.

Switch mode power transformer is used in switching power supplies and DC-DC converters. It provides a storage element for transferring energy from input to output in discrete packets as required in switching power supplies, regulators and converters. It has several basic topologies such as push-pull, flyback, boost, forward, buck and bridge.
