To build a circuit you need a different diagram showing the layout of the parts on stripboard or printed circuit board. The actual layout of the components is usually quite different from the circuit diagram. To read more articles like this one from LawncareGrandpa.CIRCUIT SYMBOLS 101 | CONNECTORS 101 | CABLES 101 | LAMPS 101 | LEDS 101 | RELAYS 101 | SWITCHES 101Ĭircuit symbols are used in circuit diagrams which show how a circuit is connected together. Hopefully this has cleared up your issue with on/off switch with your Stihl or other brand of lawn care equipment. ![]() If it is the issue, your best bet is to get an authorized repair done, which usually entails replacing the switch. With this handy device, you can test the leads on your switch to see if it is the problem. Testing a bad switch to determine if it is the problem is best done with a multimeter that can be picked up from a local hardware store or from the online retail giant, Amazon. The I symbol or 1 if you are computer language minded is for On or initiate, and the O symbol signifies killing the power or off. Knowing how your switch works on your Stihl or other brand machine is important and fairly straight forward. The Final Touches On A Stihl On/Off Switch… Any value higher/other than 0 or OL indicates a fault in the switch. ![]() The multimeter should give a 0 or OL reading, which shows the flow of current. Next, move the switch to the “off” position, ensuring the leads stay in place. If you get a value significantly lower than 1, the switch might be damaged, which disrupts continuity. If there is continuity across the switch, the multimeter will give a 1 value. With the help of a friend, move the switch to the “on” position and place the multimeter leads on the terminals that were previously hooked up to the machine’s electrical leads. Separating the leads will result in a value of 0 or OL (no continuity). A 1 reading means current flows freely between the two leads…which means there is continuity. Set the multimeter to the Ohms setting and select a scale that produces a reading of 1 when the leads are touching each other. The next step is to take your multimeter and join the leads together. Use a screwdriver of appropriate size and shape to separate these panels or handles and disconnect the switch from its electrical leads. If the switch is on the machine’s main body, you will have to remove a panel or two. Some switches are on handles, which often requires the separation of those handles. Next, you should note the position of your switch and determine how you will have to disassemble the machine. Safety first, of course, so you want to be sure your trimmer/saw is off and cool before you start opening it up. Of course, to be sure that the switch is indeed the problem, you will have to dig deeper. It’s not unheard of for an operator to have to yank out sparkplug wires to cut off a trimmer or chainsaw that keeps running despite attempts to disengage the switch. Defective kill switches can lead to problems like failure to start and failure to…er, kill, the machines in question. The kill switch is one of the parts that can give you headaches. Unfortunately, Stihl machines (like many others) can fall victim to certain problems that disrupt their operability. ![]()
