+    Switch(; state_init = false, Gon = 1e5, τ = 1e-3)
+
+An electrical switch that is controlled by a boolean input.
+
+# States
+
+    - See [OnePort](@ref)
+    - `state(t)`: Boolean input
+    - `state_filtered(t)`: Filtered delay of state(t)
+    - `G(t)`: Conductance
+
+# Connectors
+
+    - `p` Positive pin
+    - `n` Negative pin
+    - `input` [RealInput](@ref) Input of type Bool. false: switch is open. true: switch is closed.
+
+# Parameters:
+    
+    - `state_init`: Initial switch state of type Bool. false: switch is open. true: switch is closed.
+    - `Gon`: [`S`] Conductance when switch is closed.
+    - `τ`: Parameter for filtered delay.
