All Series actuators can be fit with one set of fixed auxiliary switches These are a
single set of switches which activate before the travel limit switches Adjustable
auxiliary (Mid-Travel) switches can be fit as single independent switches or in sets If
fitted as a set one of the switches in the set will activate before the other Each
switch set is activated independently from other switch sets
The maximum number and configuration of switches depends on Actuator size and
