The Different Types of Safety Switches

One of the most important parts of a building is its safety switches. These safety devices are used to turn off or on electrical equipment within the structure. Electrical equipment can range from power tools, refrigeration units and even computer systems. If an electrical circuit is tripped by a faulty switch, it can cause a deadly accident. The American Society of Safety Engineers recommends that all buildings with electricity install safety switches. But how long do safety switches last?

Safety Switch Basics

A safety switch is designed so that it can be easily installed. It comes with an indicator light that tells the user when the battery needs recharging or when the breaker has blown out. Because it has a safety guard on the outside, it can’t be turned off by anyone other than the person who has installed it. Even a child can quickly disable a safety switch. This is one reason why it’s best to have them professionally installed.

An older safety switch may not automatically sense an electricity flow. Because newer ones are manufactured to be sensitive to the current in a wiring system, they will sense any potential danger. This means that if someone trips a wire, the circuit breaker will automatically trip, the power will turn off and the safety switch will turn itself off. These newer safety switches are also referred to as P-type.

The actual safety switch itself is very small and can’t be seen. It’s usually about the size of a coin. To activate the safety switch, you must either press a special button on the face or push a lever located inside the cover of the safety switch.

Types of Safety Switches

There are two different types of safety switches: positive-active and neutral. The positive-active safety switch is designed to sense any potentially dangerous electrical current. Once an electrical current passes through the safety switch, it will turn itself off immediately and send a signal to the circuit breaker. When this type of safety switch is tripped, it will automatically send a signal to the fire department.

The neutral safety switch is similar to the positive-active safety switch. However, it has been designed to sense a different potential electrical hazard. If a person trips this safety switch, the alarm will not turn on. Instead, it will call the fire department for help. Because of this, the neutral safety switch is often used for unplugging the power source or for turning off the central heating and air conditioning systems in large buildings.

Some safety switch is buried deep into a ground hole. These are known as safety switch boxes. The reason these safety switch boxes are buried is so that if there were ever a fire, the fire hazards would be trapped within the box. To activate the safety box, you would need to first pull the safety box out of the earth. Then you would plug the safety switch into an electrical outlet in the area where the safety switch was located.

A few years ago, the older safety switches only had one contact. Nowadays, however, newer safety switches have two contacts. This allows the electrician to not only detect any fire but also manually switch the safety switch off. Due to this extra measure of security, safety switch boxes are being replaced by safety switch sensors.

Installation

There are safety switch types that are installed at the wall or ceiling. In these cases, a small electrical charge is provided to a firing circuit so that when the electrical current is applied, the circuit is triggered and the switch turns itself off. However, this type of safety switch is not very useful because it has a very short life expectancy. After the one-hundred anniversary of the first use of electricity in the United States, the long-life safety switch will be phased out.

One thing to keep in mind when using safety switches is that they are required to be installed properly. Most states require that safety switches are installed at the appropriate points. However, some states do not require any kind of installation. If your state does not require the installation of safety switches, then you need to check with your local fire department to ensure that safety is being maintained. Remember, good safety habits are hard to do away with, but you can start them today!

It is also important to keep in mind that some safety switches are required by the Occupational Safety & Health Administration (OSHA). Under the regulations, a safety switch must be installed where it can be easily accessed by employees. Additionally, the safety switch must be labelled with the symbol for which it is designed. Finally, it is important to make sure that a safety switch has an effective communication system between the employee using it and someone in the company who can respond.
