Current flow regulating stuff.
| Class | SwitchMixin | |
| Class | Switch | A switch using the XSPICE analog switch model. |
| Class | TempShort | Logarithmic analog switch set to temporarily short out two nodes with a smooth transition between normal and shorted modes. |
| Class | GangedBreakers | Two 80A DC circuit breakers ganged together with each other and a 0.5 A DC breaker, originally intended for PV ground-fault protection. |
| Class | CurrentLimiter | Limits the absolute value of current flow between b and b to Imax with a small series resistance and reverse current from a behavioral current source: |
| Class | InrushLimiter | NTC thermistor inrush limiter. |
| Class | Ammeter | Provides a voltage on output node 'amps' that equals the current flowing from 'inp' to 'out'. |
