GP/ML/TR Design Features
Among the advances AGASTAT control relays offer over existing designs is
a unique contact operating mechanism. An articulated arm assembly
amplifies the movement of the solenoid core, allowing the use of a short
stroke coil to produce an extremely wide contact gap. The long support
arms used in conventional relays are eliminated. Both current capacity and
shock/vibration tolerance are greatly increased, as well as life expectancy.

whose main gap is at the center of the coil. A shoe is fitted to the core
which overlaps the yoke and further increases the magnetic attraction.
low mean turn length and also assists heat dissipation. Since the
maximum travel of the electromagnet does not provide optimum contacts
movement, an ingenious amplifying device has been designed.

each other as can be seen in the illustration. The center of the W mecha-
nism is connected to the moving core of the electromagnet and the two
lower points are connected to the moving contacts.
contacts sets of the relay. The outer arms of the W mechanisms are leaf
springs, manufactured from a flat piece of non-ferrous metal. These outer
arms act as return springs for their corresponding contacts. This provides
each contact with its own separate return spring, making the contacts
independent.

circuit, thus retaining the high DC efficiency of the electromagnet. The
current peak on energizing is also eliminated and consequently the relay
can operate with a resistance in series (e.g. for high voltages or for drop-
out by shorting the coil). The use of the rectification circuit offers still
other advantages. The same model can operated at frequencies ranging
from 40 to 400 cycles. Operation of the relay is crisp; even with a low AC
voltage, there is a complete absence of hum and vibration.
