In order to avoid the spurious relay switching, I would like to build a control in such a way that the relay stays in the excitated state for 10 seconds after the control signal has gone low. I would like to build such a control with a single coil bistable relay. Does the following description make sense?
The relay set comand is given by the input signal . In order to build the reset signal, I would like to use a monostable with a time constant of 10 seconds . The output of the monostable is an input of a NOR gate . The second input of the NOR gate is the input signal. the output of the NOR gate is the reset signal.
Are there other driving method apart from the H-bridge in order to drive a single coil bistable relay giving separate set and reset signals?
If the drive circuit operates well, there is no concern of "spurious" relay operation.
Relay coils are best driven by MOSFETs, and across the coil, connect a reverse diode so "swallow" overvoltage pulse when he current is cut.

For single coil bistable relays, you have to reverse the coil's polarity. So if you don't want to use a bridge, then you would have to have a negative voltage source.
