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. | |||
