| '''SPST''' || Single pole, single throw || One-way || Two-way || A simple on-off switch: The two terminals are either connected together or disconnected from each other. An example is a [[light switch]]. || [[Image:SPST-Switch.svg|100px]]
|-------
| '''SPDT''' || Single pole, double throw || Two-way || Three-way || A simple changeover switch: C (COM, Common) is connected to L1 or to L2. ||rowspan=2| [[Image:SPDT-Switch.svg|100px]]
|-------
| '''SPCO'''<br/>'''SPTT, c.o.''' || Single pole changeover<br />''or''<br />Single pole, centre off ''or''<br />Single Pole, Triple Throw|| || || Similar to ''SPDT''. Some suppliers use ''SPCO/SPTT'' for switches with a stable off position in the centre and ''SPDT'' for those without.{{Citation needed|date=July 2008|reason=SPDT is specifically constrained to two positions, and CAN NOT have three, and suppliers catalogs and literature have been inaccurate for my entire career in electronics, or nowadays thirty plus years!

|-------
| '''DPST''' || Double pole, single throw || Double pole ||Double pole || Equivalent to two ''SPST'' switches controlled by a single mechanism || [[Image:DPST-symbol.svg|100px]]
|-------
| '''DPDT''' || Double pole, double throw || || || Equivalent to two ''SPDT'' switches controlled by a single mechanism: A is connected to B and D to E, or A is connected to C and D to F. ||rowspan=2| [[Image:DPDT-symbol.svg|100px]]
|-------
| '''DPCO''' || Double pole changeover <br /> ''or'' Double pole, centre off || || || Equivalent to ''DPDT''. Some suppliers use ''DPCO'' for switches with a stable off position in the centre and ''DPDT'' for those without.
|-------
| || || Intermediate switch || Four-way switch || ''DPDT'' switch internally wired for polarity-reversal applications: only four rather than six wires are brought outside the switch housing; with the above, B is connected to F and C to E; hence A is connected to B and D to C, or A is connected to C and D to B. || [[Image:crossover-switch-symbol.svg|100px]]<!--should we also show the symbol we use in the multiway switching diagrams further down the page here?
