I'm trying to activate an electrical deivce using DTMF signals. I found a circuit that i attached which uses a relay each to turn the electrical devices (device 1, device 2 & device 3) on/off. Could someone tell me what type of relay is this and where i can find a datasheet for it? Thanks.

Ok thanks. Is there a relay you could suggest i use that could activate an air condition or oven or such high powered device? I'm very much new to this. Thanks

I'm looking for The 5Y5W-K Relay mentioned above to purchase...Or any other relay with same specification that capable of controlling a lamp. Any links where i could purchase any relay to do such would be much appreciated.
Thanks.
Use the 5V relay to activate a power relay. 12 and 24V coils have much more power than 5V relays which are commonly used for signal transmitting.
The higher the coil power the faster and tighter close the contactors, hence less contact burning will occur switching high current devices like heaters and coolers.
