AI Thread Summary

Using two different switches for low and high voltage sources in electric motors, such as lift machines, enhances safety and operational efficiency. Low voltage switches are smaller and easier to operate, reducing the risk of accidental activation. This separation also minimizes the danger associated with high voltage, making it safer for users. The design ensures that operators can control the motor without directly handling high voltage components. Overall, this dual-switch system improves both safety and functionality in electrical engineering applications.

Why do they use two different switches, one for the low voltage source and another for the high voltage source, to operate electric motors such as lift machines?

Welcome to PF!

It is easier to flip a low voltage switch than a high voltage switch because they are physically smaller

Thanks Russ.
Does it also mean it is safer ?

Thread '3-terminal device external modeling'

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...

Thread 'Question about the voltage between two charged capacitors'

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...
