The switches in the RK2001 boiler controller seem to have a limited life. This controller is used on the orlan boilers and others.
A replacement switch i have used is available from Mouser electronics p/n: 611-PVA10AH11.2NV2
The pin spacing is identical to the originals, so unsoldering the old and soldering in the new is the fix. The shaft on the switch is longer than the original stubby switch that uses a push pin to activate. just let the shaft protrude thru the front panel.
The holes in the front panel may need trimmed as well as the switch shaft to fit thru the hole... no longer using the push pins used with the original switches.
Hope this provides new life for some old controllers.
