In New Zealand, the standard height to place a light switch is typically around 1200mm from the finished floor level. This measurement ensures accessibility and ease of use for most people. It is important to follow local building codes and regulations when determining the exact height for a light switch installation.
Under the NZ Building code light switches are to be placed level with door handles typically at 1000mm (AFFL) above the finished floor level. This is to aid persons with a loss of sight to find the switches easily.
The National Electrical Installation Standards (NEIS) recommends wall switches to be installed 48 inches (AFF) above the finished floor to the center of the device.
It is generally not recommended to use a 120v light switch in place of a 125v switch. The voltage rating of the switch should match the voltage of the circuit to prevent potential safety hazards such as overheating or electrical arcing. It's best to use a switch that matches the voltage of the circuit.
Yes, you can replace a traditional light switch with a toggle switch outlet.

To remove a 240-volt light sensor and return to switch operation, you can simply disconnect the light sensor wires and reconnect the original wires for the switch. Make sure to turn off the power supply before doing any electrical work and follow proper safety precautions. If you are unsure, it's best to consult a licensed electrician for assistance.
