Waterproof Light Switch are specially designed to be used in wet and damp locations such as bathrooms, pools, and kitchens. They are not only water resistant, but they also feature a snap-on wallplate that protects the switch mechanism and makes it easy to clean. The mechanism of a waterproof light switch is completely sealed so it cannot be exposed to moisture, and the lead wires are encased in thermoplastic rubber to protect them from being touched.
There are a few different kinds of waterproof switch types available, including toggles, rotary, and rocker. Some are intended for lighting only, while others can control a variety of devices such as ceiling fans, exterior lights, and gates. Many come in single-gang and double-gang options for controlling multiple devices.
Single pole (SP) switches are the most common kind of light switch. They have two brass-coloured screw terminals and a ground wire screw. One of the screw terminals connects to the hot power-source wire, and the other connects to the fixture. Most switches don't connect to the neutral circuit wire, but some do.
Dive light switches are typically toggle-style. They have a lever that is covered with rubber moldings to help keep it dry and sealed to the housing of the dive light. There are also rotary and rocker-style dive light switches that don't require a lever, and they can be used in the same way as other types of switches.
