This lock is designed for use in an EVSE (fixed or portable Electric Vehicle Service Equipment or charge point) socket OR Type 2 male charging socket on an EV.

It is intended for attachment to a Type 2 male or female socket made by Duosida (Dostar) but it may fit other makes.  It has 4 connection wires 600mm long.  The red and white wires take a momentary 12VDC connection to activate the solenoid and extend or retract the locking pin (which is designed to engage with a mating hole on the plug that is plugged into the socket).  Reversing the polarity of those 2 wires reverses the motion of the solenoid and hence the locking mechanism.  See photo for polarity effect.  Without power the solenoid and locking pin remain in the state last activated. 

The lock could be used, for example, in a DIY EV wired to a simple DPDT switch within the cabin.  Flip the switch one way and it locks the charging plug into the EV's charging socket.  Flip it the other way and the plug is released.  A wiring diagram for this function can be requested on purchase.

The other 2 wires (blue and yellow) are connected to an internal switch which reports the state of the lock; locked (switch closed), or unlocked (switch open).

See photo for dimensions.  Weight:- 90g.
