In a material world, there is only one material which scores above the rest, when it comes to electrical switches - UREA FORMALDEHYDE. Known for its self-extinguishing properties. Used world wide by reputed manufacturers of switches. To prove our point, we conduct a Glow Wire Test on our switches. 850 degree Celsius and 30 seconds later, the switch made of Urea Formaldehyde gets depressed and turns black where the red, hot probe touches it.
