Selecting the best possible switch for every application

摘要

How do you ensure you make the right switch selection for every electrical application? Tony Hankins, managing director of Rowe Hankins Components, the UK distributor for Marquardt switches, offers the following guide. Nearly every electrical device has at least one switch. We take their safe, efficient and reliable operation for granted, but selecting the correct switches can be confusing for the designer and engineer. Incorrect specification can have serious consequences for product reliability and reputation. In selecting a switch, safety always comes first. Select a reputable manufacturer with proven ability to design, deliver and supply product that meets relevant European, North American and national test and accreditation standards. And select a switch with the correct electrical rating and characteristics, including factors such as correct resistive and motor loads and tolerance of transient in-rush current on start up.
