The lucent gasket is used as induction-voltage-limiter and self-illuminating gasket instead of a common elastomer-gasket between solenoid and the female connector.
The lucent gasket is available for connector type SAW in different variations.
The lucent gasket consists of an electrical switch (SMD-technic), that is covered by elastomer.
When the lucent gasket is applied to the solenoid, it is contacted electrically.
If supply voltage ist applied, the gasket illuminates.
If the supply-voltage is turned off, the gaskets electrical switch works as a induction voltage-limiter.
