Short Description

All wet areas need to be protected by a safety switch, however weatherproof light switches can further reduce the risk of electrocution. Weatherproof light switches are usually designed for outdoors and may consist of a rubber seal either behind the switch button protecting the internal wiring or covering the switch button. Therefore, wet fingers pressing the switch are at less risk.
Weatherproof enclosures or covers for switches and general power outlets (GPOs) are also an option.
There are Australian Standard safety requirements for the location of GPOs and light switches in wet areas.

POINTS TO CONSIDER
Weatherproof light switches are NOT WATERPROOF and therefore do not eliminate the need for a safety switch. The rubber seal may make the light switch more difficult for people with limited finger dexterity to operate. Weatherproof light switches do not come in rocker style.

When choosing a weatherproof light switch enquire about the level of Ingress Protection (IP) it has. IP rating refers to the level of resistance a fitting has to foreign objects and water. The first digit refers to foreign objects such as dust and the second digit refers to water protection. For example, IP65 would have 'complete protection against entry of dust and protection from a low-pressure jet of water from all practicable directions.' Refer to AS 1939 Supp 1 (1990) for IP ratings.

Factors To Consider

Electricians state that if the water spray from a shower, including hand held showers, can reach a GPO or light switch even with a shower recess barrier in place, the switch should be relocated outside of the bathroom.

Standards

Specific Australian Standards or other Standard(s) may be applicable for materials, manufacturing processes, or installation of some types of equipment. Compliance with relevant Standards is indicated by written certification that a product has been tested and assessed as compliant with specific Standards. Purchasers are advised to check with the supplier or manufacturer of this item as to its compliance with relevant Standard(s).

Refer to AS/NZS 3000:2000 for bathroom zoning, which indicates the safe location of GPOs and light switches.
AS 1939 Supp 1: 1990 refers to Ingress Protection ratings.
