E. MECHANICAL LIMIT SWITCHES
The mechanical limit switches are independent devices in-
stalled on the yoke in linear units and in the feedback housing
area of rotary or drive units. Electrical connections are made
directly to the switches. Position will be indicated regardless
of actuator power status.
