Push-pull type mag switches

[grumman41]

Is anyone familiar with the early style "push-pull" type mag switches found on early cubs? Any safety or operational considerations? Are there any new switches that would be legal replacements?

I have a 1938 J-3 and would like to get back to these original type switches.
