A four-way switch is represented by which symbol?

Explanation:
A four-way switch is the device that sits between two three-way (SPDT) switches and swaps the traveler connections, allowing two conductors to be connected either straight through or crossed depending on the switch position. In many standard diagrams used for NOCTI practice, this four-way switch is represented by the symbol labeled S4. It’s a double-pole double-throw arrangement, handling two travelers at once, which is what distinguishes it from the SPDT symbol used for a single three-way switch. The other symbols correspond to simpler switch types: a single-pole switch handles a single circuit, and SPDT represents a three-way switch, not a four-way.
