    Waytek carries the toggle switch guards in four different colors, red, green, blue, and yellow. Minimum order is 4 but they are only $1.29 EA. www.waytekwire.com/products?pSearch=toggle%20switch%20guards&sc=1413&Toggle-Type=Safety-Cover Read this topic online here: http://forums.matronics.com/viewtopic.php?p=454758#454758

    Thanks Bob for your time!!! > If you have dual, independent main busses with cross-feed capability, then 'endurance' bus adds no value. The only reason why I want an Avionics bus is to turn off unnecessary electrical loads on the system during starting. I presume the Garmin 650 and the Dynon ADS-B and transponder are not susceptible to power surge issues during engine start and since I will have two Optima batteries this is all way overkill. The left bus is powered by the SD-20 and it has a Dynon SV-1000 with its own GPS and Dynon radio and the right side bus will be powered by a SD-60 and it will power the Avionics bus with a Garmin 650 (radio and nav). Here is the anointed military switch I am going with=85only $14.00. http://www.skygeek.com/honeywell-micro-switch-1tl1-3-switch.html .. THANKS AGAIN!!!

    + Alternator Switch??? I want to utilize a master switch like the Honeywell 2TL1-10A for the Master/Alternator switch in the Z-14 DBDASB. I like it because it has locking positions. The data sheet switch contact description did not look like I expected it to. Can someone PLEASE look at the data sheet below and tell me if it will work for this application??? .. THANKS!!!

    Yes, if I am interpreting the datasheet correctly, that switch will work. Mount the switch with the keyway down. Connect the alternator field to teminals 2 & 3. Connect the master contactor to terminals 5 & 6. As for the current rating, I do not understand it. But since the maximum current under certain conditions is 20 amps, then most likely the switch will handle 5 amps at 12 vdc. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=454771#454771
