Question: Technician A says a switch can be tested with a voltmeter. Technician B says to use a fused jumper wire to see if the switch is operating. Who is correct?

Answer: Both Technician A and Technician B are correct, as different methods can be used to test a switch depending on the situation and the type of switch being tested. Technician A is correct in stating that a switch can be tested with a voltmeter, while Technician B is correct in suggesting the use of a fused jumper wire.

Testing a Switch: Which Method is Correct?

31 Jul 2021

Explanation:

Testing a Switch with a Voltmeter: When testing a switch with a voltmeter, the voltmeter is set to measure the voltage at the switch terminals. The switch is then activated, and the voltage is checked to see if it has changed. If the voltage changes, it indicates that the switch is functioning properly. This method is useful for quickly determining if the switch is working correctly in electrical circuits.

Testing a Switch with a Fused Jumper Wire: Using a fused jumper wire involves physically testing the operation of the switch. The fused jumper wire is connected to the switch, and a fuse is used to protect against electrical issues. The switch is activated, and the jumper wire is used to verify that the switch is functioning properly by checking if the circuit is complete. This method is often used in conjunction with a voltmeter to provide a thorough test of the switch.

In conclusion, both methods of testing a switch are valuable tools for technicians. The voltmeter test is effective for assessing the switch's functionality in an electrical circuit, while the fused jumper wire test is ideal for physically verifying the switch's operation. Technicians can utilize both methods to perform a comprehensive evaluation of the switch.
