Power to electric Shower

Hello our electric shower is not working for the second time I've changed this switch twice now and there is a strange smell coming from it what is the issue. Its a pain not having the second shower not working.

My x-ray vision isn’t working today. Need to see the connections to the back of the switch.
PS turn the power off before you remove the switch plate.

Almost certainly burnt out from the description.

Sounds like a loose connection the switch has allowed it to burn out

As above , the wiresmay be loose and arcing over time. If so, you need to trim the wires back (hopefully there will be enough slack to do so.
