The DPS 40 (twin electronic switch) is an electronic switch operated by means of a magnet. It is mainly meant to switch supply voltages of receivers / servos, multi cylinder CDI Ignitions, electric retract gears or similar equipment.

A big advantage of electronic switches in comparison to mechanical ones is in general their higher reliability as far as vibration resistance is concerned. Another advantage of the electronic switch is given by its practical ability to withstand an unlimited number of switching cycles.
Electronic switches have no moving parts like contacts which would be wearing out during switching processes, therefore their durability is extremely long. Moreover, they are not prone to spontaneous and unexpected false tripping with known disastrous effects. Last but not least, electronic switches offer much lower inherent transient resistance in comparison to mechanical switches.

The electronic switch DSP 40 does operate  with the aid of a magnetic switch which can be fixed to the fuselage or elsewhere. The system becomes switched on or off with application of a special magnet.

The DSP 40 is able to switch the supply voltages of receivers and servos, CDI Ignitions, electric retract gear supply and can also be used for other DC switching tasks.

Especially suited for mid and large size models using e.g. a retract set or large multi cylinder CDI for a gas engine.
