Valiant combi boiler

[mgdave]

I have replaced the diaphram in the diverter valve on my boiler but there is a small plastic or nylon lever that actuates the micro switch . the lever seems too weak and needs replacing resulting in the hot water only working sometimes but not every time a tap is opened. My question is where can I obtain this part if it is available . any help or advice would be much appreciated
