12 Volt Relay - change over

Change over. 20/30A. 5 terminals (6.3mm blade). Metal mounting lug can be removed if necessary. (B type pin configuration)

These relays are also available having an internal diode across the the coil connections (85 & 86) to reduce the voltage spike across these terminals when the coil is de-energised. This is particularly important if the relay is being controlled by some form of electronic switch (such as a transistor) rather than by a normal mechanical switch, as the voltage spike can damaged sensitive electronics. The majority of applications will simply require the standard non diode relay (140206).

Suitable relay sockets are 140301, 140303, 140304 & 140305
