Ross Shorting Switch Relays & Deadman Kill Switches

High Voltage Relay
120 amp RMS / 30 kv

(KV) 23598-800559
Ross high voltage relay. Unique double pole, double solenoid design. Safety solenoid must first energize to unlock armature. Then, main armature solenoid can be energized to move shorting bar to bottom contacts. Conservative continuous rating: 120 amps RMS, 30 kv. 5-1/2" x 6-1/2" x 10-1/4"H. NSN: 5945-01-258-3951.
 

Automatic Shorting Contactor
for Harris Transmitter

 
(KV) 992-4651
Automatic shorting contactor for Harris transmitter. 240 vac, 60 Hz solenoid pulls bar up. Bar drops - shorting posts when voltage is removed. 6" x 5" x 15" high.

High Voltage
Deadman Safety Switch

(KV) 938-4307
High voltage deadman safety switch. Spring loaded, normally closed. 6.5" long fiberglass rod is connected to silver plated disk that is routed to ground through two, 20k, 25 watt resistors.

At resting position, disk contacts three acorn nuts set on ceramic insulators. The procedure would be to tie HV wires to acorn nuts. The unit is mounted inside the power supply so that when the door on the back closes, it presses on the fiber rod holding the disk off the acorn nuts. When the door opens, the rod spring forces disk to close on all three acorn nuts taking the voltage to ground through the resistors.

 

2 Pole High Voltage
Deadman Kill Switch

(KV) 7486297G3
General Electric 2 pole high voltage deadman kill switch for transmitter. Each pole has thick aluminum disk at ground potential via braided strap. Disk rests on three ceramic insulators to which your high voltage leads attach. Fiberglass piston is depressed by closed cabinet door holding shorting disk off insulators. Spring return draws disks down to insulators taking any voltage to ground.

Measures 2-3/4" x 6-1/2" x 4" high + 3-1/4" out front for plunger. Made for Harris broadcast.
