trigger type: low level trigger (cw-020)
load capacity: ac 250v/10a or dc 30v/10a
voltage: 5v dc input
indicator leds: red for power (pwr), green for switch status (sw)
terminals: standard no (normally open), com, and nc (normally closed)
perfect for
smart home automation (lights/fans)
arduino & raspberry pi projects
diy automated irrigation systems
electronic door locks
why buy?
plug & play: easy 3-pin input (vcc, gnd, in).
