- "do not fix things on the Sabbath" ban[s] completing circuits
- "do not break things on the Sabbath" covers breaking a circuit
sound extremely convoluted to me. A switch's express purpose is to break and complete circuits to direct current. It is part of the object's usage, part of the creator's intent on the object's utility. It has modes of operation where the circuit is broken and complete by design. The saner interpretation of this law IMO would be along the lines of "if a switch got stuck on a Sabbath, good luck on the energy bill, mate".
I have one of those trash cans with a pedal that opens the lid. It is a switch but none of it is electronic. Are Jews not allowed to operate these contraptions on a Sabbath too? It arguably introduces a break in the object, namely the opening for the trash can. Heck, does Jewish law even allow opening trash cans on a Sabbath, at all? By such broad applicability, the only difference between any lidded trash can (a closed object most of the time) and an electric circuit is the presence/absence of current. Can a Jew unlock padlocks on a Sabbath? What about opening doors?
(FINAL NOTE: HN mostly has charged---pun intended---discussions over things we deem ridiculous. Such discussion is NOT my intent here. I know J. Random Netizen like me isn't going to change Jewish culture in two paragraphs. I just wanted to waste actuations of my mechanical keyboard to register my astonishment and confusion over this interpretation.)
