Product Description
Float Level Switch is a simple mechanical assembly widely use in multiple application for all kind of liquid level detection in tank.Level switches are "no” type and "nc” type. no type i.e. normally open type, means the current do not flow through switch till it achieves certain level. in case of nc type i.e. normally close type, initially current flows through the switch till it achieves certain level. The single pole double through type gives both no & NC signal at a time called as SDLT type.The float switches work in all three conditions of no, nc or spdt type, whether the current passing through it or not.

Working Principle:

  • The working principle of float level switches are based on one magnetic property termed as repulsion.
  • If same poles come into the contact of permanent magnets located in the stem and in movable float of level switch, it shows it actions and moves upward and downward.


Float level switches designed for a variety of small and medium level detection of atmospheric and pressurized tank, live remote indication signal, level alarm, applicable to a variety of health, toxic, corrosive and explosive media gas dangerous places. There are a variety of installation, applicable to all forms of container. Float level switch adapted to control the operation of the pump to maintain the liquid level; controlled automatic loading and unloading tank; controlling level or supply of signals, such as tanks, automatic cleaning system, hydraulic tanks, low pressure boilers, waste water treatment systems.


  • Level switches developed by us has a capacity to measure or detect the level from smaller to higher length. It is available from one float to multiple floats, which gives indication of different levels of the tank.
  • Techinstro automation also manufacture specially made explosion proof level switches for hazardous area in industrial uses.
  • In some critical application, level switch give two signals at a time, for such condition spdt level switches are also available.
  • Level switch gives the best results with the low power consumption, hence we offer level switch in 230v ac with the current ratting up to 5. Our switches are leak proof, so no maintenance required.
