23 Apr Factors to consider while operating a safety switch
A safety switch is nothing but a switch that is basically used for disconnecting the manufacturing equipment and heavy machinery from its power sources. Safety switches are basically needed when you need to disconnect your equipment from their electrical sources, due to the need for repair, maintenance and of course, in times of emergency stoppage. Safety switches are also known as disconnect switch or load brake switch. It is a must to have safety switches especially if you have a factory or industry since safety switches are National Electrical Code requirements in all the factories and industries. This is done for safety purposes.
Why should we use safety switches?
There are various reasons why using a safety switch is absolutely a must.
- It provides you protection against over current.
- It provides you protection against heat generated damage.
- It provides you protection against short-circuiting.
- It provides you protection against circuit overloads.
Types of safety switches you can find.
There are primarily two types of safety switches that you will find. One is Fusible Safety switches and the other is Non-Fusible Safety Switches.
Now let’s talk about the factors that we have to keep in mind while operating a safety switch.
- The first and the most important point is mounting is when you are mounting, dismounting, wiring or even inspecting a switch, always remember to turn off the main supply before starting, otherwise, this could lead to electrical emergencies like shocks and the switch many also get burnt.
- Always remember using switches in an atmosphere consisting of combustible or explosive gases is like inviting death. Using switches when combustible gases and explosive gases are around results in making the switch heated which eventually leads to explosions or horrifying fires.
- Never drop safety switches. Also, make sure to never disassemble them. Dropping or disassembling switches not only bring a change in their characteristics but also causes damage, electrical shock or even burning.
- Always keep in mind to select suitable switch ratings only after you have confirmed the contact load. The contact load is a huge factor that you need to keep in mind while operating a safety switch. If the contact load is too excessive then the contacts might get welded or shifted. This will further result in short circuits, or burnings after the power supply are turned on.
- There are some steps you need to follow while wiring for your own safety. Remember to stay very cautious while wiring. When you are doing the wiring part, make sure you do not have the main power supply turned on. The charged terminals should be definitely not touched while the power supply is on. Touching the charged terminals while electric supply is on may result in electric shocks and burning and other electrical hazards. It is always better to follow the step by step procedure for the wiring and soldering work. If the wiring and soldering are not done properly, the switch might get overheated when the power supply is turned on and this will eventually lead to electric shocks.
- The durability of a switch plays a very important factor. The durability of a switch varies greatly with switching conditions. Always make it a point to use the switch in actual conditions for the actual use before you actually start using the switch. Using a deteriorated switch continuously for too long might result in insulation failures, switch damage or switch burnouts also. To avoid these electrical hazards, always make sure to use the perfectly proper and functioning switch which is not deteriorated.
- Before you start using a switch, do all the possible tests because once it is done, there is hardly anything you can do to avoid accidents or electrical emergencies.
- Selecting the correct switch plays probably the most important role. You have to select the correct type of switch to avoid accidents, but for that, you have to know what is the correct type of switch. The selection guide can help you with this. The Selection Guide helps you choose a suitable switch for the rated current, operating load, actuator types, and of course, the operating environment. Never forget to use sealed switches for the room having leakages for water to pass easily. We all know what horrific electric hazards can water cause if it comes in contact with switches. To prevent these accidents, make sure those rooms have sealed switches.
- Haptics which has recently become very important in the automotive industry plays a very crucial factor here. Now, what is haptics? Haptics is basically the sound and feel of the switch when you operate it. Haptic plays an important role in letting the customer know if the switch has correctly been operated or not.
