why mosquito bat makes noise when it hits with a insect?
Answer Posted / pavan
A mosquito bat consists of three layers of mesh, the outer
two being one terminal and the inner being the other
terminal of a transformer that provides high current at low
voltage.
When a insect comes in between the two meshes it creates a
closed path for the current to flow. since it is a high
current it results in a sudden surge which creates a spark
that eventually ionises the air molecules in and around the
arc. this sudden ionisation of air creates the hissing
sound.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
