- This relay is slighty different than [Relay JQC-3FF-S-Z](https://old.stadtfabrikanten.org/display/TH/Relay+JQC-3FF-S-Z) (Logic Level difference due to other layout of resistors)
- measured: relay switches off properly at >= 3.2 V and switches back at <= 1.1 V

This relay is used to control the LED stripes and spots of Trikarus.
