[TenTec] ROCKER POWER SWITCH FOR PARAGON II AND 961 PS

[Bob McGraw - K4TAX]

Something doesn't seem correct with your failure experience.

I have power supplies and radios that have these as the original power 
switches.  Many of these get turned on and off daily.  I have also repaired 
may of the power supplies and radios of these brands/models and I can't 
recall the last time I had to replace a switch.

The switch in the Paragon II only handles a small amount of DC to switch a 
relay, where the major amount of DC current is handled by a power relay.  Of 
course the switch in the 961 is switching 120 VAC unless you have it 
configured for 230 VAC.  The latter might be of concern but I have no 
experience in this area.
