I'm looking for a compact servo mount that includes micro-switches mount points. I have installed Arduino driven servos for point control on a couple of layouts now, but I'm still looking for a decent mount. I find that the mounts can be overly large (there are a number of 3d print designs), or home rigged solutions using aluminium channel are problematic when it comes to mounting micro-switches Any thoughts?
You could try Tam Valley http://www.tamvalleydepot.com/products/servosaccessories.html I don't think they have micro-switches on the mount. They rely on the control board to do the external switching. Kind regards Geoff
If you are a MERG member, they have 3D printed ones available which take up to 4 microswitches at a very reasonable price. Unfortunately only sold to members, but they have many other worthwhile kits available, and we have a number of MERG members (including myself) on the forum who will doubtless agree. Keith
Its well worth Joining MERG as their prices are well below anything comparable offered elsewhere and your annual membership can be recovered in just one purchase A big thumbs up for their servo controller and mounts. Paul
There are a couple of our members big on MERG. I'm sure Paul_l has there servo mounts. or did he 3D print his own .... mmmm
You're right Toto (not often you'll hear that being said), Victoria Road used the Merg Servo mounts with at least one micro switch attached - the mount can sope with up to 4 micro switches. There is a thread on the MERG Servo Mounts showing the simple construction price is now £6.72 for 6 ( = £1.12 each), for those MERG members with access to a 3D printer, the files are available to print your own.

and his first foot is firmly on the slippery slope, one slight push and the dark side will have another victim . Also worth looking at while your in the kit locker, is the horizontal mounts and signal mounts. Next is how are you going to control the servo's ? On my Victoria Road layout I have 6 point motors (Tower Pro SG90 Micro Servo's) mounted on MERG servo mounts, controlled by 2 MERG Servo4 devices. The control of the Servo4's is via an Arduino based DCC accessory decoder. Paul
I used I/O extension boards like these driven by Nanos. Control is by switches on my plank, and momentary pushbuttons on the club layout fiddleyard. Personally I'm not too interested in DCC control of points, I like buttons or switches on a mimic panel. I'm interested to try out the PWM boards with I2C comms. There is also some demand from club members to have slow motion of points, so some changes to the firmware. The Arduino sketches I wrote myself. 45 years of programming before I retired probably means that I've been skirting the edge of the dark side for some time
I used 8 of the servo mounts and 2 Servo4 devices to operate my two double track level crossing gates. Totally in agreement regarding point control, I much prefer DP centre off switches even though I am fully DCC for loco operation. Keith.
The club fiddle yard I have converted consists of 5 sidings controlled by 4 points. The pushbutton control sets a route and the Arduino changes all the points necessary for the selected route. Works pretty well and has been reliable so far. There is a second fiddle yard with 6 sidings and 5 points that I hope to convert next week. The main problem is retro fitting the servo mounts around the layout supports. Some servos have to be mounted backwards which means a change to the firmware to operate that point backwards. All good fun
This one looks interesting. With I2C control apparently you can daisy chain them, each with its own address, plus they supply the power for the servos rather than the Arduino https://www.ebay.com.au/itm/16-Chan...e=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649
