E Switch

What is an E Switch?

An E Switch is an electronic replacement for the mechanical switch used in radio controlled models. As all power switching is by semiconductor devices, E Switch guarantees a long and reliable life.

How does E Switch work?

E Switch uses a locking toggle switch to switch low resistance semiconductor devices on and off. E Switch has been designed, in the event of a toggle switch failure, to switch on and continue to supply power to the model.

Why use an E Switch?

With the increasing size and weight of RC models, the current drain from the receiver battery pack is placing increasing demands upon the mechanical switch contacts. This in turn is leading to deterioration of the contacts causing increased contact resistance and premature failure. A standard servo such as the Futaba FP-S148, when rotating with no mechanical load, draws around 150mA. Therefore a four servo model can be expected to drain at least 600mA, and possibly over 1000mA when under load. The switches supplied by RC manufacturers are rated in the 500 to 1000mA range, and therefore are barely adequate for the purpose.

Advantages of E Switch

E Switch has a current rating limited only by the associated wiring and connectors, and the internal resistance of the battery pack. All current loading is transferred to a low resistance Mosfet, leading to an overall increase in reliability. E Switch is highly recommended for large, heavy, or fast models using high torque servo's of high current drain, models using more than four servo's, or where failure can lead to damage or complete loss of the model.
