Customer questions

Q The Netherlands Jos NollenYour drawing says "switch". Should I connect an external potential contact there or a 12 Vdc pulse signal? Answer this question
Q The Netherlands AnoniemHi, I bought one of those and I hooked it up to 12 volts. When I push the button there is a relais-clicking-sound and the red LED lights up or turns dark. But no matter what I do, between the three output-contacts the voltage is always 0. What am I doing wrong? View 1 answer   |   Answer this question
Q The Netherlands NDoes the relay remain in its current position after power failure? In short, no start or end position, just like an impulse relay? Answer this question

Customer Reviews

The Netherlands
In the service I often have to deal with expensive replacement electronics. That's why I myself sought a solution that is cheaper and effective: a pulse switching monostab. originally costs € 300 net at the manufacturer. (this costs under € 20 With this circuit I can achieve the same, and customers also like it.

You can also use this relay HCW-M02 with a control device (e.g. esp8266), not just with an external push button. You can't find that anywhere on the internet. Set left control terminal first low and then high then toggle the relay. digitalWrite(esp_pinX, LOW); // making pin low delay(100); digitalWrite(, HIGH); // making pin high, Toggle relay on or off depending on state
