Description
Suitable for novices: DIY Light-Operated Switch Kit has few parts and detailed installation steps, which is very suitable for novices to exercise welding ability..Bright trigger working mode (jumper cap 1-3 position): When the photoresistor senses that the external light changes from no light to light or the light gradually increases, the relay pulls in..Dark trigger working mode (jumper cap 2-4 position): When the photoresistor senses that the external light changes from light to no light or the light gradually weakens, the relay is closed..Two output modes: The JMP2 jumper cap is set to make the relay work. If the relay passive output function is not used, the relay can be set to not work to reduce the power consumption of the circuit. When the jumper cap is in the 2-3 position The relay is allowed to work, and the relay is prohibited from working when the jumper cap is in the 1-2 position..Wide range of applications: DIY Light-Operated Switch Kit can not only be used in schools to exercise students' hands-on ability, but also in various electronic welding competitions.
