Triple Pole Single Throw (TPST) switch used to "park" a 3 phase Lakota (True North Power) wind turbine.
3 Phase 60 Amp knife switch used in the ribbon cutting ceremony for the "Switch Opening" reception of 2004 June 17th, for the Urbine project. This switch was selected, in part, because of its epistemological value, i.e. that its function is made visible by the open design in which we can see the handle that holds the three knife elements to switch them simultaneously.
