Question

State whether the given statement is true or false:
We must not touch electrical switches with bare hands.
- True
- False

Answer 1

Electrical switches are made of insulating materials, like thermoplastic. And it is the property of insulators to not allow electricity to pass through them. Hence, even if we touch electrical switches with bare hands, we will not get shock, cause the switch blocks the electricity to reach up to us.

Complete step by step answer:
Electrical switches are made of insulating materials, like thermoplastic.
Insulators are those materials which doesn’t allow electricity to flow through them. For example, rubber, plastic, paper etc.
So, generally there is no issue in touching the electrical switches with bare hands because since switches are insulators they don’t allow electricity to reach up to us and we don’t get any shock.
Hence, the given statement is false.
But for safety precautions in any case the insulating material is defective or damaged, so we might get shock. So, it is advisable to touch electrical switches with any insulating material in between.

Note:
It is generally advised to not touch any electrical appliances with wet hands, because water (not pure) is a good conductor of electricity and our body too, hence although the surface of the appliance could be an insulator but water may get seep through any cavity and after coming in contact with the circuit it will allow the electricity to pass through our body and we may get shock.
