modelForcedSwitch
Forced switch, 1-phase
Extends from Partials.SwitchBase (Switch base, 1-phase).
Information
Allows switching of single conductor (of totally one or two).
Switching by forced change of current-voltage ratio.
'closed' and 'open' determine the mechanical switch-position.
Electrically the switch is 'on' if it is 'closed', whereas the currents start decreasing exponentially, when it is opened.
The transition between the 'off' conductivity (epsG) and the 'on' resistivity (epsR) is continuous with an exponential relaxation function
f = (exp(-dt^p/2) - exp(-1/2))/(1 - exp(-1/2))with
dt relative time measured from switching instant t_relax relaxation time p power of exponent
