Push button and two-way switch: advantage and disadvantage


Many like to tinker and do not want to call a professional when it comes to tampering with the electrical installation of the house. However, before embarking on such an activity, it is essential to know certain basics. In electricity, you can choose between a push button and a two-way switch. Knowing its roles, advantages and disadvantages allows you to make the right choice.

Push button and switch back and forth: what is it?

Generally, push buttons are intended for different uses, including lighting, door opening, doorbell, or timer. Today the push buttons that have appeared on the market are more designer. The spring loaded devices are small and the buttons have backlighting for easy location at any time. The operation is quite simple: when you press the button, the current starts to flow but the button returns to its initial position.

The switch compared to the push button is more aesthetic and is available in various forms, ranging from the square model to the mini-lever recessed in a quadrilateral housing. The most common type comes as an uncovered tab in a square or rectangle case. The functions of the two-way switch are a bit more limited unlike that of the button. A switch is usually used to control a lighting system or to pass current through a given circuit.

The specifics of each accessory

The association of push button-panel with module is commonly called a remote control switch. In terms of connections, this system has the advantage of having many control points. It is simple to use and set up, giving it pride of place in the emergency device category.

A switch is connected to a lighting system, whether spotlights or a ceiling light. If conventional switches only have one control point, the one called back and forth has two. It can even go up to three control points, associated with a permutator. Clearly, with a two-way switch, you can turn on a bulb from more than two different places. This is practical in a large family, a hotel, or even a work place.

Push buttons and switches: advantages and disadvantages

On classic push-button prototypes, you often have to keep the pressure to make contact. The latter are also known to generate parasitic pulses called rebounds after having put their finger on them. To overcome this drawback, pushbuttons with locking in one position have been designed.

Some new models can even be part of a home automation system. Thus all the equipment of the house can be controlled by a single box, including lighting for example. In this case, users won’t even have to move from their bed to switch off before sleeping. This device is also easy to install in parallel connection with only two wires. The concern is when changing the bulb. Indeed, by the arrangement of the button, it will be a little difficult to recognize if the bulb is powered or not.

The two-way switch is made for large residences with several entrances. Some innovative so-called wireless versions greatly contribute to the style and interior decoration. Thanks to these electrical components, the walls will be spared and the property free of kilometers of electric wires. This jewel of technology works like a micro-transmitter and is powered by a battery. These products are usually sold as a kit with a switch already connected to the electrical installation.
