The General Radio 1432-U Decade Resistor was introduced in Catalog Q (1961) and remained available through Catalog S (1965).
The Type 1432-U is decade resistance box is comprised of four Type 510 decade resistance units in series for a total resistance of 111.1 Ω. The 510 decade units use an 11 position switch, the first position shorts the decade the folowing positions increase the resistance by a factor of 1. The decade switch is what's refered to as a make before break configuration, regardless of the position there's always a continuity at it's terminals. The terminals are Type 938 equiped with a shorting link to the case. The decades are housed in an aluminium case shielded and insulated from its resistance termials.
Specifications
- Total Resistance:111.1 Ω
