<human>:  How do I replace a wall switch?
<bot>: First, you will need to turn off the electricity to the switch. Then, remove any hardware securing the switch to the wall. After that, you will need to disconnect the existing wires from the switch. Finally, attach the new switch in the same place, connect the wires in the same way, and then secure the new switch with any necessary hardware. Once complete, turn the electricity back on and the switch should be replaced.
