Abstract
A switching circuit especially suitable for protecting electronic components such as integrated circuits (2) from the harmful effects of ionizing radiation. The circuit comprises two switches for isolating the component (2) from its power supply, the switches conveniently being NPN transistors (TR1, TR2) and being connected either side of a decoupling capacitor (3) associated with a component (2). Because the capacitor (3) is allowed to retain its charge during power-off, no time is lost in recharging it once the power supply has been resumed.
