Switch Motor and Relay (DZ-1008) wire connectors to avoid soldering ??

I know about wire twists I was looking for a single plug-in friction or snap connector with six connectors for the small wires.

I note that in your application you are not using the white (or yellow) wire so it just an on/off relay. In mine the relay's  blue wire is track power and the switch is between the white and gray wire. 

Do what works in the telco business, they always use small wires. By these butt connectors.

They are epoxy filled. Quick, easy and permanent. ACE Hardware, Menards and Home Depot carry them in small quantities too, but the price is better on Amazon.

Buy these butt connectors.....

That's what I use!  You don't even have to strip the wires. Just make sure both are fully inserted and squeeze.

How about WAGO Lever Nuts?

My interpretation of what the OP is asking for is a 6-position (or whatever) connector system rather than connecting 1 wire at a time using screw-nuts, Wago connectors, or what have you.  In which case, the so-called Dupont terminals/connectors might work.  It's just that the Arduino explosion/phenomenon has made these connector quite the value especially if eBay is an option.

A possible gotcha is this connector system is not "polarized" or "keyed" so you could mate the male to female backwards.  But, as shown above for a 6-position example, one should assume that the wires of like color mate/align, and presumably do the male-female mating ritual once in a lifetime!

If really pressed for $, you can "crimp" wires into the inserts using a needle-nose plier rather than a crimping tool.  The inserts support wire between 18-26 AWG or so.

If you're going to crimp wires, go with a decent polarized connector.

How about a recommendation then?! 

Even with a polarized connector, the user must insert the right wire into the right position in the first place.  Likewise, with the individual one-at-a-time method, the user must be mindful to twist or mate the red to red, black to black, etc..  That said I don't see it as an onerous burden when using a 6-position male and female pair to orient the two housings correctly.

As for the Dupont type, one technique that can help are so-called keying pins or keying plugs.

You would need to use a larger position connector.  So maybe an 8-position rather than a 6-position.  You place a plug(s) on the female housing side in selected position(s).  The male side must then have NO male pin in the corresponding position or else the housings won't mate.  Obviously this is not fool-proof but it is common practice.  Needless to say the keying plugs cost MORE than the metal crimp inserts and a quick search on eBay found zero listing for them!  I have been known to jam a wooden toothpick into the housing hole to be plugged and snap the toothpick off at the surface...voila!...a keying plug.

I use them for my 14 ga power feeds and really like them. However, for small sized wires like on the DZ1008 (22ga?), they don't seem to hold too well.

I have about 35 2500 switch machines and a bunch of the relays.  I used the WAGO connectors exclusively.  I have two, three & five connectors, love them.
