Questions & Answers

Can you tell me what the amperage is ?

Currently, I am utilizing a 110 V DC generator to run my water mill. The switches I use are for charging batteries. Assuming the switch is closed (meaning the amperage goes through the switch), when I want to charge batteries I force DC currents through the battery I would like to charge (it currently has 3 A but I believe it could handle significantly more due to the quality of the contacts). Arking should only be used with a voltage below 36 volts though make sure you don't overdo it

How much current does each of these switches draw?

The regulations differ from one country to another, but I am not familiar with them. Although, they should be able to handle 5 A, there is a point where the voltage should not be greater than 36 volts. This means that most of these switches can only handle a certain power (Amps x Voltage)

This is the ideal dipole for linked dipoles

4/5

With these knife switches, I can connect my indoor three band dipole antenna to a line of three antennas. It is good quality enough for QRP transmissions. I would not trust them for QRO use or in the outdoors, however.

There is no plating, but real brass

5/5

Those little switches are great. All the material is brass and not just plated, and stainless screws are used.

It is a cut out of an antenna

5/5

It is used to disconnect during thunderstorms by sitting at the end of a long wire antenna.
