If you plan to install heavy-duty electrical appliances (needing 240 volts or more power), you can choose a double-pole switch for them. Electric furnaces, air conditioners, water heaters, or hot-tub heaters are suitable for double-pole switches.

It is a switching device for traveller wires between the two three-way switches. It is used with three-way switches to create a circuit with three controlling switches.

- Dimmer Switch – A dimmer is a switch that allows you to adjust the brightness and intensity of your light fixture. There are many kinds of dimmers. For example, a rotary dimmer switch has a knob that you rotate to adjust the brightness level and press to switch the light on or off. You can find dimmer switches that are single-pole, double-pole and three-way.
- Wall-Control Dimmer Switch – A wall-control dimmer switch gives you the flexibility to adjust brightness levels, and it can also be programmed to turn on a combination of lights at the touch of a button. Use it to control more than one light in your room.
- Occupancy Switch – An occupancy switch is equipped with a sensor that detects when someone walks into a room and turns on the light. The light stays on for a preset amount of time, and if the sensor does not detect any motion for that period, it switches off the light to conserve power.
- Speciality Switch – Specialty switches are equipped with unique functionalities to serve different purposes in your home. Some speciality switches have timers that switch lights on or off based on the timing, and others have touchpads, time-delay mechanisms, and dimming functionalities.
