Using a continuity tester on the terminals see if there is continuity when the switch is turned on.
Test a 3 way switch turn off power to the switches at the circuit breaker and using a tester make sure power is off. The alternative circuits appear to require one less wire but in reality it is usually necessary to return the com connection at the second switch position to the first switch or the rose or light fitting which typically needs a wire. A circuit with 2 switches and 1 load would be 3 way. Touch the other probe to the colored wires one by one. Place leads of continuity tester on the two terminals with power off. Turn off the power at the circuit breaker remove the 3 wires from each of the switches and make sure that none.
Check for voltage on switch terminal. In this step you will be turning the power back on do not touch any of the wires previously removed with.
