RO-1 RO-2
Pull or Pressure

Operating pressure 4 kg

Pressure

Operating pressure 60-100 kg

RO-3 RO-4
Pressure release

Operating pressure 2 kg

Pressure Release

Operating pressure 2 kg

RO-5 RO-6
Pressure

Operating pressure 130-160 kg

Pressure, for use on Railway lines.

Operating pressure 2-4 kg

RO-7 RO-8
Pressure

Operating pressure 20 kg

Pressure

Operating pressure 3-6 kg.  This is a mine igniter rather than a boobytrap mechanism.

RO-8II RO-10
Pressure, this fuze cannot be neutralized.  This is a mine igniter rather than a boobytrap mechanism. Pull/Pressure, a warning goes with this fuze that it cannot be neutralized.

Operating pressure 4 kg

RO-30 ECHRo
Pressure for use on railway lines.  This one has an adustable number of pulses meaning if you set it for 10 pulses, it must be pressed 10 times before it initiates the charge.

Operating pressure 2-4 kg

Electrical/chemical time delay, can be set for 1-124 days
UZC UZO
Used for igniting pyrotechnic signals, smoke or illumination or for simulating an explosive boobytrap.

Operating pressure .5 kg

Used for igniting pyrotechnic signals, smoke or illumination or for simulating an explosive boobytrap.

Operating pressure .5 kg with a delay of 6 seconds.
