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. The [[510]] decade units use an 11 position switch, the first position shorts the decade the following positions increase the resistance by a factor of 1. The decade switch is what's referred 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 equipped with a shorting link to the case. The decades are housed in an aluminum case shielded and insulated from its resistance terminals.

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.
