Knife Switches

Type A and Type DL heavy-duty knife switches are configured for single or double throw.
Nov. 17, 2005

The design allows for modifications to handle polarity reversals, high frequency, high voltage, air operation, and remote operation. Type A switches are front connected with adjustable silver-plated contacts and insulated bases and have a 30 through 30k-A rating. Back-connected Type DL switches have no base plates and a 30 through 10k-A rating. Available options include a padlock attachment, a front-mounted handle (for single-throw switches only), auxiliary limit switch or lowcurrent knife switch actuated by the main switch (for remote indication), handle guard (standard on 600-V and above switches), and a field-discharge attachment for opening a generator field.
