The green / red on / off switch on my Unimat 4 has decided to play silly beggars and having initially declined to stay 'on' when I release the red button, it now comes on without my touching the green button as soon as I switch it on at the mains but it won't switch off when the red button is pressed!
There is presumably a fault with the integral relay but electronics is not my forte. Dopes anyone know how this fault might be cured or where I can buy a replacement switch assembly?
Thanks in anticipation.
