When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true. Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for designers and engineers to understand how to pick the right switch for their product.

Freeway capable EVs are more expensive than slow EVs because you need more batteries (sometimes: could use buddy pairs at lower voltage) and a high voltage controller. The same motor can often still be used, just by advancing the brushes, and maybe adding a blower to keep it cool. So, it seems to me that the best place to focus efforts to making freeway capable EVs more affordable (under $1500?), is to focus on the controller. About $1200 or so can be shaved off the cost of a new controller.
