Why is My Light Switch Hot?

  • The main reason for the switch getting hot is, for using a switch for a long time, or it can be dirty inside or it can be rusty.
  • And this rust creates problems in current flow like resistance. 
  • If the amount of dirt or rust is excessive, it can cause a fire.
  • Because of the temperature, it can melt the upper cover of the switch and cause an accident.
  • So, it is better not to use this type of switch. If you find this type of switch, turn it off immediately. 
  • Another reason for the heat is, some switch works at low voltage.
  • Their cover is made of plastic and the bit is low quality. 
  • It can work under 50-100 voltage. But if the limit exceeds it gets hot.
  • That’s why always use good quality switches for AC current.
  • Also, phase neutral short can cause heat and can cause shock.
