We often take switches safe, reliable and efficient operation granted but it should not be taken that way. We should take a more cautious approach towards switch selection. Here below are listed some of the precautionary steps that you must follow before buying electrical switches for any device or appliance.

Follow the Safety Standards

Safety for the people, home and device are of utmost priority to every one. So always prefer a reputed electrical hardware manufacturer with proven ability to design, deliver and supply products (especially safety switches) that meets the accreditation standard followed in your country or region. Always select a switch with correct electrical rating and characteristics, considering factors like precise resistivity and motor loads and tolerance of transient in-rush current on start up.

Know the operating environment
The surrounding environment in which the switch operates is an important consideration while selecting switches. Before buying an electrical switch you must consider that will it be exposed to exceptionally high humidity/moisture, temperature, dust or any other hazards? Make your choice according to the operating environment. Switches are available in many materials (Find switches by material) that can withstand high temperature and flames. Also you can prefer switches specified with heat resistant, flame retardant cases. and with dust and splash protection.

Style quotient is important as well

Though the style quotient is of least value when considered from safety and functionality point of view but when we take aesthetic considerations in view it roars back to the top priority. You should carefully think twice about the size, colour, shape, switch action, texture, and markings before buying switches for automotive, medical devices, computer hardware, electronic appliances, and many other similar applications. More than the aesthetic consideration, the style and design of switches can affect the appearance, usability, and user's perception of the value and quality of the device.

Assured Performance
Switches having more than 2000 annual operation cycles must be tested for 50,000 cycles. Gold plated contact on switches that are infrequently used adds to the reliability.

Mode of Operation
It should be considered carefully that what mode of operation suits the need best. There are numerous choices like toggle, rocker, push button, touch switches, rotary, slide, open or closed snap action or foot switches. It should also be considered that whether you need single, double or multiple-pole switches?

Consider carefully the benefits of standardization of switch types, the ease of fitting the correct choice of terminals to suit the production method. Even if you are a bit confused then you must seek advice from the distributor.

It is very important for us to select a switch that is safe, effective and reliable and that fulfills the requirements of the application. Failing to meet the needs precisely can lead to higher service costs, premature failure, outages for the user.
