Technical term for the rotary switch I need
Posted by pelerin on Saturday, January 11, 2020 10:31 AM

Hi Folks,

Can someone please tell me the correct name for the type of rotary switch I need to order for the following project? I want to incorporate one 3-aspect LED signal to one end of the mainline of a 2' x 8' portable "time saver puzzle" type  HO layout. That end of the layout leads to a cassette that serves the double function of (a) loading and unloading the train onto/from the layout and (b) if desired, use the cassette as an additional yard area, making the switching puzzle easier for smaller kids. The layout is going to a foster home for kids. This is a simple, basic DCC, bulletproof layout. I want to install a simple, basic, bulletproof 4-position rotary switch. I have already tested the signal and it works with the layout's DCC power.  It has a resistor on one wire, and three wires (red-yellow-green) for the appropriate aspect signal.  None of the electrical supply stores near my small town has the switch, and I need to know what to call it so that I can order it on the internet. It has to have one input to route power to one of the three aspect lights, plus a "dead" (off) circuit. So, it is a 4-position switch. 

Please note that, with the best intentions, people are going to want to suggest different ways of doing this, but I beg of you, all I want to do is the rotary switch, not one of the thousand better ways of doing this. It is not a block light, it is not an occupancy light, it is a humble traffic light... This is not a contest layout or a layout to dazzle model railroad experts.  All I want is the name of the switch to look for. Thank you for your understanding!!!

Louie

Welcome
 
SP4T Rotary Switch.
 
 
I buy SP12T with a adjustable stop then set how many positions I need for each application.

I agree with Mel's response. A rotary switch will do the job.

I really like the 12 position rotatable switches with the adjustable stop, I buy them in bulk and use them for all kinds of goodies.  They’re great for testing projects, and cheap too.
