High Voltage Deadman Safety Switch

Part Number:
(KV) 938-4307

Product Details:
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.
