How do you properly test the safety circuit?

Testing the safety circuit involves checking each switch independently to ensure that every component functions properly on its own. This method isolates each switch from the circuit, allowing you to accurately determine if each component is working correctly without interference from others. It helps identify any faulty switches that may not operate in a multi-switch configuration.

Individually testing switches ensures that they open and close properly, thereby maintaining the integrity of the safety circuit. This approach is vital in safety-critical systems, where even one malfunctioning switch can compromise the entire system's safety.

While checking voltage levels, inspecting connections, or testing all devices at once may provide some information about the circuit, they do not ensure that each switch operates correctly on its own, which is the primary goal when verifying the safety of a circuit. Each switch must be confirmed to be reliable and functional individually to prevent false readings and ensure overall system safety.
