Multronics Model 5080 RF Contactor has been designed to handle high voltage RF switching. Corona or pluming is prevented by means of special corona gradient shields. Silver-plated beryllium-copper contact cups assure maximum surface contact for all switching modes. Switching is accomplished with two heavy duty solenoids with molded and encapsulated coil windings that require only momentary application of control power. Two protective limit switches that are normally closed during the switching cycle serve to remove control power when the cycle is completed, and two additional (normally open) limit switches provide electrical interlock and impulse for indicator circuits. All limit switch functions are brought out to a 16 pin terminal board.
Positive transfer action is accomplished with a spring loaded breechlock mechanism using a minimum 15 pound force. The specially treated and virtually indestructible (NEMA GPO-3) material used in arms and crossbars provides added strength and durability, as well as voltage and current handling capability without arcing. Servicing and parts replacement are simplified, since basic parts are accessible without disassembly.

The Model 5080-220-1 RF Contactor is designed primarily for high power RF Circuit applications at VLF, LF, MF, and HF. It can also be used as an excellent high voltage DC switch for transmitter applications.
