12V Change Over
Description
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).
