The General Radio 1432-Z Decade Resistor was introduced in Catalog R (1963) and remained available through Catalog S (1965).
The Type 1432-Z is decade resistance box is comprised of six Type 510 decade resistance units in series for a total resistance of 11,111,100 Ω in steps of 10 Ω.
The 510 decade units use an 11-position switch, with the first position shorting the decade, and the following positions increasing the resistance by one step. The switch has a make-before-break configuration, i.e. regardless of the position there is always continuity between the terminals. The terminals are Type 938 equipped with a shorting link to the case. The decades are housed in an aluminum case shielded and insulated from its resistance terminals.
Specifications
- Total Resistance: 11,111,100 Ω
- Number of Decades: 6
