hi guys
could you please look over the attached circuit , i have built this on the breadboard and works correctly but putting into multisim it does not work and there representation of a relay i have never used before and need some help on tweaking the settings on the relay properties to correspond to my bread board circuit !!! unless you see any other errors also please advise below are my relay info and attached schematic.

my actual relay specs from my breadboard are as follows
HRS4H-S-DC 9V
NO -10 AMP 250 V
NC 6 AMP 250V
10 AMP 120 VAC
10 AMP 24 DC
cheers

Remove the wire from K1/D1 anode to ground.
Connect Q2 collector to this node.
Connect Q2 emitter to ground
Connect K1/D1 cathode to +9V

Your breadboard is probably wired differently.

Have fun!
 
Q2 is in the wrong place. Put it between the relay coil and ground. Since it is an npn transistor the base must be ~ 0.7 volts above the emitter; however, you have connected the emitter to the 9v supply, the highest voltage in the circuit.
