![]() ![]() Note that there are differences between British and American terminology when it comes to the colloquial names for common switches.For instance, if you're installing a toggle switch to control a car's hydraulic system, you'll probably want a switch with multiple poles to control the hydraulics for the different sides of your car and/or multiple throws so that you'll be able to set the hydraulics to "off" or varying degrees of "on", rather than just simply "off" or "on." However, if the device you're attaching your toggle switch needs more than basic on-off control, you may need a more complicated switch.Read through the instructions or paperwork that come with the switch to make sure it will work for your purposes. Ensure that the switch is compatible with the device you intend to use it for. To ensure you select the right toggle switch, check with the manufacturer or ask a salesperson to help you.Usually, for simple on-off capability, you'll want an SPST switch. A throw refers to the number of positions a switch has. In electrical terminology, a toggle switch can have one or more "poles" and "throws." A pole refers to the number of circuits controlled by the switch-usually, this is the number of outwardly-visible "levers" on the switch. ![]() Select a switch with the appropriate number of "poles" and "throws" for your purpose. When the solder begins to melt, withdraw the soldering iron tip and allow the melting solder to flow and cover the wire-terminal joint. Heat each terminal with a soldering iron while holding the end of solder wire in contact with the terminal (but not in direct contact with the soldering iron tip). If the toggle switch has solder connections, bend the ends of the wires around the switch terminals.If your toggle switch has screw terminals, loosen the terminal screws, loop the ends of the supply wires and hook each loop over a terminal screw so the loops point clockwise around the shaft of each terminal screw.If your toggle switch has wire leads, twist the end of each lead to one of the supply wires (or pigtail extensions) and twist a wire nut over each wire connection until they're tight.The way you do this depends on the type of toggle switch you have. At this point, you've made a break in the device's supply wire, you'll need to add your toggle switch in the middle of the break so that it can regulate the flow of electricity through the circuit. Connect the supply wire to the toggle switch. ![]()
