PINTUHOKI88 Pushing the switch actuator in one direction causes the relay contacts to close; pushing it in the opposite direction causes the relay contacts to open. Toggling the switch disconnects one "traveler" terminal and connects the other. Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. Readers in most other countries should read "two-way" or "SPDT" for the United States "three-way"; and "intermediate", "crossover" or "DPDT" switch for the United States "four-way".|{3|4|5|6|7|8|9|10|Three|Four|Five|Six|Seven|Eight|Nine|Ten} Ways To Reinvent Your Slot One
