Oddly they require a combination of solder and screw terminals to connect them, so I removed the terminals and just soldered these connections. The metal plated through holes weren't exactly the spacing of my perforated board, but I managed. Note that the negative power supply is switched (VCC connected directly) and you cannot switch voltages higher than the trigger voltage. There is a trigger current that supplies the LED, among other things. I've used them to drive the LEDs of non-contact liquid sensors (like the B07FC5RGC7 element) which can only source a few mA despite being rated at 100mA. It was the perfect power amplifier.
