With electronics it was common to have SPST , SPDT , DPST , SPDT, (in theory you could have more poles / throws in electronics but in practice building home electric circuits those are the only 4 I ever came across in stores for. Other then maybe dimmer switchs which is more of a continuous throw based switch. And once I saw a 3 throw based switch the center was off state
SPST (is just regular on and off switches )
SPDT ( are standard 3 and 4 way switches used for controling an object at multiple locations pretty standard uses 14/3 red/black combo ..etc)
DPST ( is like a 2 regular on and off switch so you can control 2 different circuit on the same switch at the same time for instances)
DPDP ( are like a 2 regular 3 /4way switches builtin analogy would be from the SPST to DPST )
Curious I have looked for switches for 240 volt applications but I only see the 120volt rating on label. I know some switches are rated
for 15amp or 20 amp. But I am wondering do they make 240volt ones or are the ones that say 120 good also to uses on 240. I would assume so but I don't see much of these at stores like home depot. Probably not used often enough maybe. Or maybe the electrical supply stores would care more of a selection.
Note: Of course they have kill switches and other switches for higher voltage but I am talking for residential house building. I normally only see SPST , SPDT (3/4way switches). Are there any others that they usually uses in homes or is it basically those 2 types with maybe dimmer switches as well.
I don't know how common it is to uses a DPST to control 2 lights/appliances on separate circuits in home/residential application.
What I am getting at is in theory knowing the inner workings of the different switch types allows you to open up new worlds in designing circuits in a house but in practice (and under the house codes ) how often does one use the other types of switches (other then the on/off , 3 , or 4 way switches )
Also it seems to me that one could if he wanted to get the same 3/4way switch effect by using more 2 way switches
and 14/3 or 14/4 wiring in creative ways. So one would not need the 3/4 way switches ever if he want to .. obviously for conveniences because one could build the built-in circuit of the 3/4 way switch it self into his circuit using 2 way. But I have to say the 3/4 way switches make it easy to rig up or much more easy.
I know I repeated myself on this thread a lot but I am curious how often the professionals uses types of switches in homes. Also if there is any difference when it comes to the commercial/industrial building other then higher rated wire/switches maybe (i.e is it the same types of switches just higher rated or is it completely different)
