+# Voltage Controlled Switch
+
+The Voltage Controlled Switch block represents the electrical characteristics of a
+switch whose state is controlled by the voltage across the input ports (the controlling
+voltage).
+
+![sw_edited](https://user-images.githubusercontent.com/43288153/184137917-1e6d4b0e-42a9-4a87-80f1-9d98d2a6dc39.png)
+fig: Voltage control switch
+
+This block models either a variable-resistance or a short-transition switch. For
+a variable-resistance switch, set the Switch model parameter to Smooth transition
+between Von and Voff. For a short-transition switch, set Switch model to Abrupt
+transition after delay.
+
+When the controlling voltage is less than the Threshold voltage, VT parameter
+value minus the Hysteresis voltage, VH parameter value, the switch is open and has
+a resistance equal to the Off resistance, ROFF parameter value.
+When the controlling voltage is greater than or less than the Threshold voltage,
+VT parameter value by an amount less than or equal to the Hysteresis voltage, VH
+parameter value, the voltage is in the crossover region and the state of the switch
+remains unchanged
+
+The schematic to test the proposed voltage controlled switch is shown below.
+It is a simple circuit where a pulse source is connected to the switch followed by a
+resistor.
+When the switch is turned ON, then at the Vout the source voltage can be
+obtained, however, the switch model is given some value for Ron meaning the amount
+of ron will be offered by the switch when it is turned ON.
+Similarly, when it is turned off then it will offer the resistance set in roff.
