Thorens TD 160 "pop" revisited

I wanted to provide an update on the solution to the pop which occurred on both opening and closing the power switch on my TD 160. This switch works in tandem with the speed control selector. As many have suggested, I had a snubber installed by a friend who knew just what was needed. ( Thank you Sanjib)  

A 0.1 microfarad/450 vdc capacitor was placed in series with a 100 ohm resistor across the switch. This served to prevent the arc across the air gap. 

Problem solved! The pop is gone completely. Thanks to everyone who contributed. 

I hope this information helps others who encounter this issue. 

Apparently I've been told this is what I'm trying to remedy:

Spark Suppression circuits are designed to reduce arcing and noise generation produced in switches and relays. When a switch or relay is opened, an arc can develop across the contacts, which over time can erode the contacts.

Thank you all for very helpful and thought provoking advice. I'm going to ensure there is a proper snubber circuit including a capacitor and a resistor across the switch. Apparently, if left uncorrected it will eventually fry the contacts.

After it's all done, I'll update with details for the benefit of the next poor soul.  😉
