Switch PLECS 1.5 Online Help Switch Purpose Ideal single switch. Library Switches Description This Switch provides an ideal short or open circuit between its two electrical terminals. The switch is open when the gate input signal is zero, otherwise closed. Parameters and Dialog Box Width The width of the component. This affects both the width of the electrical ports and the width of the gate input signal. The default is 1. Initial conductivity Initial conduction state of the switch. The switch is initially open if the parameter evaluates to zero, otherwise closed. This parameter may either be a scalar or a vector with the width of the component. The default value is 0. Probe Signals Switch conductivity Conduction state of the switch. The signal outputs 0 if the switch is open, and 1 if it is closed.
