Put simply, a switch is a component that controls the closed-ness or open-ness of an electric circuit. They do allow control of over current flow in a circuit, making them very important components in any circuit which requires user control or interaction. Generally, a switch can only exist in one or two states, closed or open. With so many different types of switches in the market, differentiating them may be quite difficult. However, each switch does have different characteristics which define or differentiate it. These characteristics usually include factors such as the action that flips the switch and how many circuits the switch can control.
All switches fall into one of these two distinct categories; these are the maintained and momentary switches. The maintained switches usually stay in one state until such a time when they are actuated into a new state and then remain in that state until you act on it again. These are the most common and are also referred to as On/Off or toggle switches. There are also the momentary switches which only remain active as long as they are actuated. Unless they are actuated, such switches usually remain in their off state. Push button light switches fall into this category, activating the button usually implies pressing down on the button in some manner which then feels as some momentary control. These switches are best used for what can be termed as intermittent, user based input cases.
Typically, these switches tend to have a very nice click or tactile feel or feedback when you press them and come in a wide variety of colors, sizes and flavors. From the small to the illuminated and highly colorful, these switches offer a very wide selection option to the homeowner. It is important to note though that not all push buttons are momentary. This is because there are some push button switches which will latch into place and maintain their state until the button is pressed again to return the unit where it started.
For termination purposes, push button switches can be terminated as panel mount, surface mount or even through hole. Generally, through- hole switches tend to be larger in size than the surface mount units even though they function in a similar manner. Surface mount switches also tend to be smaller and sit flat. They normally require a gentle touch and are not built or developed to sustain significant switching force as a through- hole switch.
Just like any other switch, changing or installing a push button switch is not difficult. Just make sure you stay safe by taking all the necessary precautions before you embark on the task. Ensure that you have turned off the circuit breaker that’s powering the light circuit before you start the installation. As you unscrew the plate, never touch the sides of the switch until you have confirmed the voltage. Use a voltage tester for this purpose, this ensures that you have turned off the correct circuit breaker.
If you are not comfortable or unsure about the installation, it is always recommended that you call a qualified electrician to come and do the installation for you. Electrical installations that have not been properly done can cause significant damage not only to the home but may also harm other family members as well.
