These are "OE type" rocker switches, meaning they look OE, and fit into standard Toyota (such as in the Lexus IS300, Scion tC, Toyota Tacoma/4runner/T100, AE86 etc) blanks.  Three options are availible, the simple SPST two prong "on-off"- great for switching EMS maps, safeties, extra lights or the TokenSolutions hosted free-be "DIY fan mod", the DPST which is a four prong "on-off", great for switching on/off two things at the same time, and the DPDT 6 prong on-off-on, great for more complex installs such as interior lighting, multible EMS settings etc.
