Los cortes de encendido, Sparkswitch de Powerbox-Systems los llevo usando prácticamente desde que empecé a volar aviones de gasolina. Ofrecen una seguridad adicional sobre el control de encendido o apagado del ECU (encendido) de nuestros motores de gasolina. Si se suelta un escape o existe cualquier otro problema, puede parar el motor sin depender de la palometa del carburador. También garantiza que con el avión apagado, no se pueda poner en marcha el motor en caso que alguien gire la hélice. Por todo esto, a día de hoy, yo personalmente no montaría ningún avión de gasolina sin un SparkSwitch.
También los he usado para otros fines, pudiéndose usar como un simple interruptor en cualquier tipo de circuitería. Personalmente lo he usado para encender o apagar las tiras de led de algún corchito o similar que no llevaban controlador de luces.
Además de todo esto, es sencillo de instalar y sin programación necesaria, es solo colocar y volar.

Descripción:
The SparkSwitch is a reliable, high-performance ignition switch. The overall design of the SparkSwitch is deliberately simple, but omits no important functions. The ignition switch is immediately ready for use as supplied, and needs no setting up. The only requirement is to set up the switch channel at the RC system transmitter.
The SparkSwitch can be used to turn the ignition circuit on and off from the transmitter, and is suitable for use with power supplies consisting of NC, LiPo or LiFe cells. The output voltage is subject to linear stabilisation, and is regulated at 5.9 Volt (alternativ 7.4V and 12V): a value which is suitable for all types of ignition system. The separate plug-in ultra-bright 5 mm LED should be mounted in the area of the engine cowl, in order to indicate the switched state.
A particularly user-friendly feature is that the unit detects when the receiving system is switched off, and draws no current from the ignition battery thereafter. This means that there is no need for an additional switch between the battery and the SparkSwitch, and forgetting to switch off the ignition battery is no longer a problem.
As you would expect, the battery can also be recharged without being disconnected.
The power circuits for the receiver and the ignition system are isolated from each other by an opto-coupler, effectively preventing interference from reaching the receiver.
The set includes accessories such as two connecting leads and the LED and mount.
The SparkSwitch has also proved excellent in practice as an electronic switch for supplementary working systems such as lighting circuits.
