The pull cord switch was badly burnt. Luckily the shower stopped working before a fire was started. The customers were lucky. They had got a funny fishy smell before the shower stopped working. If in doubt please switch off appliances
and get them checked out.![shower pull cord switch2](http://www.carraherelectrical.ie/wp-content/uploads/2016/09/shower-pull-cord-switch2-150x150.jpg)
