VDE Explosion Proof 220V Float Level Switch Septic Pump Float
Cable float switch is a device used to detect the level of liquid
within a tank. The switch may be used in
a pump, an indicator, an alarm, or other devices.
When used in a typical sump pump application, the float switch is
used to turn an electric pump on and off.
As water enters the reservoir of the sump pump, a plastic float
begins to rise. The float is commonly fastened
to a rigid structure at one end, thereby, causing the float to
pivot or roll over as it rises on the water level.
A micro switch inside of the float switch is connected to an
electric pump by wiring that runs through the
chassis of the pump. Once the proper angle is reached by the float,
the ball inside runs to the low side of the
switch and completes the circuit, allowing electricity to reach the
pump motor and begin to pump the water out
of the basement or structure. Once the water has been pumped out of
the reservoir and the float reaches its
resting level once again, the ball flows out of the switch and the
contact is broken within the wiring harness,
turning off the pump motor. In this design, the float switch is
commonly housed in a copper, aluminum or tin
float canister to prevent rust and deterioration in the submerged
1. Cable Float Switch uses one-step shaping injection molding with
substantial structure, cheap price and long lifetime.
2. It has very good control effect for long distance, multiple
level control, submerged pump or liquid with grain or block.
3. Certainly it is also useful for normal liquid. It uses Micro
Switch to make connection output. Connection point capacity
10A/250VAC can start the motor equipment directly.
4. It can be regulated freely and easy to operate, convenient to
install, safe and reliable, without maintenance, non-toxic and
5. It can resist sewage so that widely used in pool in resident,
factories mines and etc., and ponds, barrel, manger and pot with
oil, acid and alkali as well as the vessel with high viscosity and
INSTRUCTION FOR FLOATING SWITCH OF ELECTRICAL PUMP
1. Fix the counterweight on the power cable to control water level.
(Counterweight is only provided at request. )
2. Connect the electrical cable with the electrical pump and then
fix it inside the water tank.
3. The length of the cable section between the fixation point of
the device and the device body determines the water level.
4. The terminal of the electrical cable shall never be immersed
into water during installation

CONSTRUCTION & OPERATION
It consist of a float integral With a 3 core electric cable.A fixed
micro switch and a moving steel ball are enclosed within the float
casing.A change in liquid level causes the float to tilt up or down
a pivot,provided in the form of an adjustable stopper or support
pipe,at an angle and in the process, actuating a steel ball to move
and operate a micro switch plunger to close or open an electrical
with potential free contacts,to operate auxiliary electrical
devices like alarm,pump and solenoid valve.
1. The core of cable is real copper not copper - covered aluminum
2. Good micro switch in the ball ensure the long life of float
3. The raw materials of plastic are brand-new with high quality
