Product description

The DPSI CUBE is a compact and lightweight magnetic switch suitable for 20 amps permanent current. The switch can be turned on/off from the outside of the R/C model using a magnet, so it is not necessary to drill any holes into the fuselage. Due to its high current rating, its low weight and its compact dimensions, the DPSI CUBE is also suitable for narrow fuselages as well as R/C cars and R/C boats.


Cable connections

The DPSI CUBE is available with 7in (AWG16) receiver and battery connection cables.

Items delivered

Delivery includes DPSI CUBE, magnet with lanyard and quick reference guide.


The DPSI CUBE can be mounted inside the fuselage, e. g. using silicone.

Note: It doesn‘t matter if the „INPUT“ or the „OUTPUT“ side of the DPSI CUBE faces the inner side of fuselage. Switching on/off works on both sides.

Switching on and off

The DPSI CUBE can be turned on/off by placing the included magnet on the DPSI CUBE LOGO on the housing of the switch for approximately one second. Alternatively, for switching on/off the magnet can be placed on the „INPUT“ as well as on the „OUTPUT“ side.

The distance between the magnet and the DPSI must not exceed 8 millimeters (0.3 inches). The switch can be turned on/off through the R/C model‘s fuselage.

Safety instructions

ATTENTION: The DPSI is turned off using a Hall effect sensor. Hall effect sensors can be influenced by magnetic fields. It may happen that the DPSI switches off when exposed to a very strong magnetic field (e.g. electric drive). Current-carrying cables also generate magnetic fields. So please keep all cables which carry a high current (>100A) at least 3cm (1.18in) away from the DPSI.
