High Voltage

Deadman Safety Switch

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

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.
