Switch rating

In the context of electrical devices, a switch rating is a specification that indicates the maximum electrical load that the switch is designed to handle. It is typically expressed in amps (A) or volts (V) and refers to the maximum current or voltage that can be safely switched through the device.

In the United Kingdom, switch ratings are used to specify the maximum electrical load that can be handled by switches, including wall switches, dimmer switches, and programmable heating thermostats. For example, a wall switch might have a switch rating of 10A, indicating that it can safely handle a maximum current of 10 amps.

It is important to ensure that the switch rating of an electrical device is appropriate for the electrical load it is intended to handle. Using a switch with a lower rating than the electrical load can result in the switch overheating or failing, and can potentially be a safety hazard. Therefore, it is recommended that you consult with a qualified electrician or HVAC technician to ensure that the switch rating of your electrical devices is appropriate for your specific electrical installation and usage requirements.
