Sonoff 4CH Pro & 4CH Pro R2 are 4 gang WiFi switches. They support switching among 3 working modes: interlock/self-locking/inching mode, and both supports to set 1-16s delay in inching mode. This feature allows you to let your switch turn on for a few seconds then goes off, which works like a pulse switch. They integrate with a 433.92MHz RF receiver module, making them possible to be controlled by RF Remote. The smart switches are DIN Rail mounted.
