Overview
The Linemaster T-91-SE is a Treadlite II series foot-operated switch designed for general-purpose and light-duty industrial control applications. This unit ships paired with the 522-B14 full guard, a steel-constructed protective enclosure that shields the switch mechanism while providing secure floor mounting. Together, they form a complete foot control assembly suitable for machinery control, press operation, and similar industrial foot-switch applications.
