Voltage controlled switch.
N+ and n- are the positive and negative element nodes, respectively. Nc+ and nc- are the controlling nodes. Mname is the model name. A switch is a resistor between n+ and n-. The value of the resistor is determined by the state of the switch.
The resistance between n+ and n- will be RON when the controlling voltage (between nc+ and nc-) is above VT + VH. The resistance will be ROFF when the controlling voltage is below VT - VH. When the controlling voltage is between VT - VH and VT + VH, the resistance will retain its prior value.
You may specify ON or OFF to indicate the initial state of the switch when the controlling voltage is in the hysteresis region.
RON and ROFF must have finite positive values.
