CRX SR4-Ti/ Cu - Quad Nichia 219C 5000K - Electronic Tail Switch

I built this light around an Emisar D4 driver and Nichia 219C LEDs.

It has an electronic tail switch to control the brightness ramping/ On, Off.

The switch signal from the momentary tail switch is conducted through an inner insulated brass tube to a sprung brass contact ring on the driver.
