Measuring the resistance of a button

AI Thread Summary
To measure the resistance of a car steering wheel button using a digital multimeter, first disconnect the button from its wiring. Set the multimeter to the resistance measurement mode. When the button is not pressed, the resistance should read as infinite, and when pressed, it should show approximately 0 ohms. This method allows you to test the button's functionality without needing the steering wheel installed or connected to the ignition. Detailed instructions emphasize the importance of ensuring the button is isolated from any electrical connections during testing.

I need to measure the resistance of a button on a car steering wheel, so my question is: how do I measure the resistance of a steering wheel button using a digital multimeter? I don't currently have the steering wheel installed yet, so can I measure the resistance of the buttons without the steering wheel being installed and hooked into the ignition/electronic? I'm an electrical newbie, so any detailed instructions on how to measure the resistance of a button is greatly appreciated.

Thanks a million!

Hi caunyd,

Most multimeters have an option to measure resistance. Is it a simple button you can press down? I suggest you to disconnect the switch from wiring, and measure between the leads. Typically, the resistance will be infinite when the button isn't pressed down, and approximately 0 ohms when the button is pressed down.

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
