Three-wire control

The basic device for remote control of the Type NR oil 

switch is a single-pole, double-throw switch (three-wire 

control) supplied by the customer. Any manual switch, time 

switch, voltage-, current- or photo-electric controlled switch, 

or similar device can be used provided the control circuit is 

energized for a minimum of 4.5 seconds for each operation. 

A connection diagram for a standard three-wire control is 

shown in Figure 2.
