3 digit decimal thumbwheel switch assembly
One solidly built temperature setpoint type switch. The first stage just has + or - and the other 3 are decimal. The output is analog coded. It can be sent to US locations for $5.00 (Priority Mail), to Canada for $5.00 (First Class International package), or most other locations for $10.00 (First Class International package).
