The Type 1432-J is decade resistance box | The Type 1432-J is a decade resistance box comprised of four Type [[510]] decade resistance units in series, for a total resistance of 11,110 Ω. | ||
resistance of 11,110 Ω. The [[510]] decade units use an 11 position switch, the first position | 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. | ||
following positions | The switch has a make-before-break configuration, i.e. regardless of the position there is always continuity between the terminals. | ||
