CAN ANYONE TELL ME IF THE TORTORSE SWITCH WILL BURN OUT IF THE SPTD SWITCH IS STUCK IN THE ON POSITION

The Torties are designed to have DC power to them at all times. They are not an instant throw switch machine. I power mine with 9 volts DC and have 12 in operation with no problems at all.

I'm almost afraid to ask how you are powering them if you had a burn out.

A Tortoise, or any other stall-motor switch machine, requires constant voltage and a very low Amperage, so a currrent-limiting resistor must nearly always be used with them, depending on your voltage source. If you're trying to use the AC accessory terminals on a power pack, you're going to burn one out, because they are meant to be used on DC power only, at no more than 12-14 volts. If you have them connected to the constant DC terminals of a power pack, you need at least a 470 Ohm resistor in the line to limit the current to the motor. I have found that the resistor provided with the Tortoise is usually not high enough, and the machines move too fast, so I change the resistor value accordingly.

hey fellows thanks
I did not burn the switches up i did have them hooked to AC on the power pack when i put them onto DC they began working . I then retraced all the wireing to my switches and found one causing a short
again thanks for the help
