Lektron LSS230 Safety Switch Relay


Also called Induction relay or Safety Relay.

This relay serves as a safety relay, which is only energized when a pulse (from the ignition coil) is present.

The gas system only works in this way when the engine is running. If the engine stalls, the gas shutoff valves will also close afterwards.


Take the pulse signal from the low voltage side of the ignition coil (-1). That is the signal that comes from the contact points or the electronic control of the ignition coil. Also called the Primary Coil Driver.


DO NOT use the high voltage wires (spark plug wires) as a pulse signal. This is sometimes used by wrapping a wire around and connecting it to the relay. This can cause a lot of noise and interference and peak voltages, causing the relay to behave erratically and fail more quickly
