Never be short of a resistor value when experimenting or prototyping when you have one of these Push Button Resistance Substitution Box from PMD Way. Simply wire it in to the circuit via the spring clip terminals, and select the required value using the push button wheel switches with easy to ready numbers. The resistance tolerance is 1% and power handling is 250 mW/0.25 W - just like normal resistors you may be working with now. Use the options menu to select between two resistor ranges: 1 M to 0.1 Ohm 10 M to 1 Ohm Don't forget to check out our full range of substitution boards if this doesn't meet your needs. And as always, all orders receive free delivery. And remember ... if you: can't find what you need not sure what to order want a bulk deal need technical support or just want to have a talk ...
