# PowerSwitch

>  A generic module that switches power based on a logic signal, needs specialization
The logic signal is active high. When left floating, the state is determined by the normally_closed parameter. 

## Init Args

<ParamField path="normally_closed" type="bool" />

## Interfaces

<ParamField path="logic_in" type="ElectricLogic" />

<ParamField path="power_in" type="ElectricPower" />

<ParamField path="switched_power_out" type="ElectricPower" />

## Global Attributes

These attributes are available to all modules and interfaces in a design.

<ParamField path="lcsc_id" type="str">
  Assign the LCSC ID of the module.

  If set, this will tell the picker to select that part from LCSC for this block.
</ParamField>

<ParamField path="manufacturer" type="str">
  This module's manufacturer name, as a string.

  Only exact matches on the manufacturer's name will be found by the picker.
  It's recommended to fill this information based on what `ato create component`
  provides.
</ParamField>

<ParamField path="mpn" type="str">
  This module's manufacturer part number, as a string.

  For the picker to select the correct part from the manufacturer,
  this must be set.
</ParamField>

<ParamField path="package" type="str">
  The package of the module.

  This drives which components can be selected, and what footprint is used.

  Must exactly match a known package name.
</ParamField>

<ParamField path="exclude_from_bom" type="bool" />

<ParamField path="override_net_name" type="str">
  When set on an interface, this will override the net name of the interface.

  This is useful for renaming nets which are automatically generated.
</ParamField>

<ParamField path="required" type="bool">
  Only for ModuleInterfaces.
  If set to `True`, require that interface is connected to something outside
  of the module it's defined in.
</ParamField>

<RequestExample>
  ```ato Basic Usage theme={null}
  import PowerSwitch, ElectricPower, ElectricLogic

  # Create normally-open power switch
  power_switch = new PowerSwitch(normally_closed=False)

  # Connect input power
  input_power = new ElectricPower
  assert input_power.voltage within 5V +/- 5%
  power_switch.power_in ~ input_power

  # Connect control signal
  enable_signal = new ElectricLogic
  enable_signal.reference ~ input_power
  power_switch.logic_in ~ enable_signal

  # Connect switched output to load
  switched_output = new ElectricPower
  power_switch.switched_power_out ~ switched_output
  load_circuit ~ switched_output

  # When enable_signal is HIGH, power flows to load
  # When enable_signal is LOW (or floating), power is disconnected

  # For normally-closed switch (fails safe)
  fail_safe_switch = new PowerSwitch(normally_closed=True)
  # This switch passes power when control is LOW or floating
  ```
