On/Off volume control

[andrefranc]

I have a transistor radio and it doesn't come on right away and then after a minute or so it starts to work. I discovered the problem is with the on/off switch as when it is not coming on I can short the switch out and it comes right on. I tried washing the switch out but still doesn't work. Where can I get another one of these little switches? It is about 3/4 the size of a dime and I think the pot is about 5K ohm. Thanks for any help.
