A power switch operable to change between a conductive and non-conductive state for use with an ignition circuit of an internal combustion spark-ignited engine and adapted to be disposed between the output conductor of a high voltage generator or ignition coil and an ancillary system, such as an aftermarket ignition system, anti-theft system or speed control governor circuit. The power switch receives a high voltage pulse-type signal from the engine's original equipment high voltage generator or "coil" and connects the primary power source, such as a battery, to the auxiliary system. Power is supplied to the ancillary system in synchronization with the output signal from the high voltage coil. The power switch is particularly adapted to permit use of aftermarket ignition systems and other auxiliary circuits with original equipment ignition systems without interrupting the electrical connections or systems that rely on signals from the high voltage generator or coil of the original engine ignition system.

[ What is claimed is:] [1.]1. In an electrical system for an internal combustion engine having at least one sparkplug for igniting a fuel-air mixture, a first circuit for generating a pulse electrical signal, a power source for an electrical system of said engine and an ancillary system operable to perform a function in response to a signal generated by said first circuit, the improvement comprising:a switch operably connected to said first circuit, said source and said ancillary system and responsive to receiving a repeating pulse-type signal from said first circuit to provide one of connecting electrical power from said source to said ancillary system and disconnecting electrical power from said source to said ancillary system.
