Reduce OCV with Low Voltage Device (VRD - 4 Volts)

Dead Man Switch
Having difficulty turning on and off your power tools?
Then zrid's new dead man switch is your solution.
Using a mechanical or wireless trigger that can be conveniently placed anywhere to switch on and off your power tools.
Now available for all types of magnetic drills.

New Line Product
Featuring a remote control on/off switch which can be used to control fans, water pumps, fume extractors, lights and power applications, etc.


General applications:

zRID.Pty.Ltd is a company committed to manufacturing hazard control devices. Featuring a unique device that incorporates wireless technology to eliminate the voltage while not welding. It can also be used to eliminate unnecessary control cable on Tig, Mig, Plasma machines.
New generation of wireless on/off switches can replace mechanical switches that turn on/off water pumps, fans, lights, electric motors, electric solenoids, valves, etc.
The on/off device can be installed in places where mechanical switches will be difficult for the operator to reach or in wet areas where it would protect the operator from possible electrocution when they are required to come into physical contact with on/off switches.
