DPS 40

DPS40 (double el. Switch) and SPS20 (simple el. Switch) are electronic switches especially designed for switching power supply for receiver / servo, switch on the ignition and the like. The great advantage of the electronic switch is generally more reliable than mechanical switches, especially in terms of the effects of vibration. Another advantage brought by electronic switch is a virtually unlimited number of cycles ON and OFF. Because the electronic switch has no mechanically moving parts, contacts, etc., these switches even greater durability. The electronic switches are unlike mechanical switches and the advantage that it can not be itself off. When switched on, the electronic switch is characterized by minimal contact resistance.

Control switches DSP40 and SPS20 is implemented using a magnetic switch that can be mounted on the fuselage. After placing a special magnet, as shown in Chapter 2, is to turn on or off the system. Switches DSP40 and SPS20, although primarily intended for switching the receiver and servos, but i find its application in other applications where it is necessary to switch the DC power supply.
