[QUOTE="SPECIAL LOCATION, post: 76713, member: 250"] All switches arc & spark when you turn them off... (Tis one of the reasons we are warned if you smell gas DO NOT turn anything electrical OFF, as spark could ignite gas!) the bigger the load the bigger the spark... the cheaper the accessory the thiner the plastic, the brighter the spark appears.. the darker the room the brighter the spark appears... All switches have a max current rating which is the amount of load the contacts can safely and regularly break without damaging the switch contacts.. e.g. welding together due to the associated arcing & sparking! e.g. 16amp/10amp/6amp etc.. rated light switch. 20amp double pole isolator switch. 100amp/80amp/60amp etc.. CU main switch. 80amp/63amp etc.. RCD etc.. etc.. [/QUOTE]
