12V Change Over

12V change over micro relay. 10/20A. 3 x 4.8mm & 2 x 6.3mm blade terminals.

Approximate dimensions 22mm x 25mm (tall) x 13mm.

These relays are also available having an internal diode across the the coil connections (1 & 2) 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 (140260).

Suitable relay sockets are 140306 and 140307
