This oldie still is a goody - except the on/off switch for the light is erratic.

Model 139.655000, has a leaf switch to connect/disconnect light circuit.

Parts no longer available from Sears, but it seems like I should be able to get such a switch.

I've cleaned the terminals, and bent the leaves slightly with varying degrees of success. I'd like to replace the switch with an "off delay" one that works.

Any suggestions?
