Roco 42605 Sleeper Switch
Operating Data
- Switching current max: 1,0 A
- Switching voltage: max: 24 V
The ROCO sleeper switch is a switching contact operating independently from the propulsion power and can be used whereever a switching impulse should be created by a moving vehicle. Special characteristics of the switch contacts are small dimensions and reliable operation; to facilitate unobtrusive installation it has been housed in a sleeper. Whenever a magnetic field is present, the contacts close and a circuit is closed. The magnets required for operation (42256) are attached for this purpose to the underside of the locomotive which should activate the switch. The magnets should not be attached too close to the locomotive motor to avoid mutual interference between the magnetic fields of the motor and the switch magnet.
Installation of the sleeper switch
The sleeper switch is inserted into the trackbed from below. The sleeper band is cut below the rail at the place where the switch sleeper should be installed. Generally, the sleeper band can be cut with a hobby saw (fig. 1). It the track has been laid already, it is recommended to lift and cut the sleeper band with a backward (saw teeth up) installed saw blade (coping or jeweler‘s saw)-(fig. 2). The cutout must be large enough so that the switch sleeper can be inserted. Note: The contact threshold is connected through a 2-pole standard ROCO connector. This connector is provided with an RC module preventing the damage of contacts due to high voltage. Do not remove this connector in any case.
Mounting the switching magnets
The rectangular magnets (42256) should be attached to the underside of the
locomotive in a suitable location. Care should be taken that the magnet will
be centered above the sleeper switch and with the longer side parallel to the
sleeper. The height of the installed magnets must be above the railhead, but
no more than 2mm. Attention: At higher speeds, it can happen that the duration
of the switching impulse is too short and the operated accessory will not
react properly. In this case it is necessary to increase the magnetic field.
This can be accomplished by installing two or more magnets are installed in a
row adjacent to each other. The magnets must be places so that their poles
repel each other (fig. 3).
