Implementation ID: electrical-switch
Reviewed: 2026-10-27

Behavior

Conserving component solved simultaneously with the connected network. Finite on/off resistance with an explicit control threshold; no arc or contact bounce

Interface

Original Lemonergy interface view. Lines identify ports; they are not a completed simulation circuit.

Ports and observed outputs
Name	Direction	Unit	Meaning
`p`	terminal	V; A	electrical conserving connection; voltage across and current through the connected branch.
`n`	terminal	V; A	electrical conserving connection; voltage across and current through the connected branch.
`current`	output	A	Recorded current measurement from the conserving simulation.
`voltage`	output	V	Recorded voltage measurement from the conserving simulation.
`closed`	output	fraction	Recorded closed measurement from the conserving simulation.

Parameters

Defaults are initial model values. Select values for your own model and operating conditions.

Configuration fields
Parameter	Unit	Default	Meaning and limits
On-state resistance `onResistanceOhm`	ohm	0.01	Resistance of the conducting branch or conducting end of the memristor model. Minimum 1e-06; Maximum 1000000000
Off-state resistance `offResistanceOhm`	ohm	1000000000	Resistance of the open switch or insulating end of the memristor model. Minimum 1e-06; Maximum 1000000000000
Switch command `gate`	dimensionless	0	Configured switch command when no external command is connected. Minimum 0; Maximum 1
Switching threshold `threshold`	dimensionless	0.5	The switch is on when its command is at least this value. Minimum 0; Maximum 1

Equations and rules

R = Ron when gate ≥ threshold, otherwise Roff
I = V/R

Limits and interpretation

Finite on/off resistance with an explicit control threshold; no arc or contact bounce
Demonstration parameters are not calibrated hardware data. Singular or incompatible ideal constraints and unsupported state ranges stop the run.
