toggle switches
1. I only realised today that normal toggle switches that need a
nominally half-inch hole have (at least) two incompatible threads and sizes of nut. 2. I have a panel that includes a toggle switch that controls the mains supply to a row of sockets, to which are connected a desk PC and two monitors. (Other peripherals (scanner, printers, etc) are on a different circuit). This switch is only operated twice a day. It has to be replaced quite often; maybe more often than once a year. The replacement is always rated at 250V, 15A. The switches have been from RS and Rapid (not all the same batch then). The mode of failure is mechanical: the toggle springs back to the ON position when switched towards OFF. Sometimes once the faulty switch has been removed it then works perfectly! It's as if simply being fixed into the panel is stressing it in some way. The switch body doesn't touch the panel. Other switches on the panel never fail, including one that does exactly the same job but supplies a different PC. I'm puzzled. Chance? Bill |
