ISO9001 CERTIFIED
PROGRESSIVELY PARALLELING (SHORTING) SWITCH
MAXIMUM ROTATION: 180 Degrees.
FUNCTION: The one piece finger brush assembly progressively connects (or shorts) together
the switch positions sequentially as the switch is rotated.
ONE PIECE FINGER BRUSHES: No mechanically or solder joined section in the solid, stress-
free one piece finger brush assembly. Solid fine silver finger brush contacts, stator contacts and
collector rings.
APPLICATION EXAMPLES: This type of switch is utilized for paralleling capacitors in capaci-
tance decade units, for varying capacity values in multiple fixed frequency generators, receivers,
transmitters, etc. It is used in many resistance bridge, strain gage and transducer applications,
syncro systems, remote controlling, and computer systems. One or more progressively parallel-
ing decks can be included in a
standard multi-deck switch to meet all types of requirements, providing it does not rotate over
180 degrees.
NOTES
Current Rating: 1 1/2 amp with standard finger brush. Resistance: 0.005 ohms.
