I am new to relays, and trying to read up. My needs are a relay that can control 230VAC min.10A(pref. 20A). It should be controlled by a 5VDC signal. One 5VDC pulse(0VDC->5VDC->0VDC) should trigger the relay to switch state, and then it should stay in that state until a new 5VDC pulse. It should preferably be mounted on a DIN rail.
1) Am I looking for a 'Latching' Relay? (Pulse part)
2) Is there 'DIN Rail Socket/Holder' for relays intended for PCB mount?
3) And of course, is there any suggestion for a component fulfilling above?
