Current Switches Buying Guide

We use a current switch while monitoring the current level in some system. It can sense a rise or fall in the level of current. When the current value goes beyond or drops below a particular value, a set of contacts change state from either an open to closed condition or vice versa. It will either alter or signal the abnormal condition of current flow in the system. Selecting a well-functioning current switch is significant to not only keep its users safe but also protect the gadgets from damage. Keeping a few factors in mind, we can choose a good current switch to serve our purpose.

External power supply

Having a current switch that needs no external power supply is more convenient than a switch that requires an external source. Quite a large number of brands sell switches that depend on the self-inductive power supply. Check the action current value. You can use a potentiometer to make adjustments. 

Response time: the shorter, the better

You want the current switch to respond as fast as possible. An efficient current switch will have a shorter response time. It acts more quickly to protect the appliance from any possible damage. Besides, it makes a switch safer. Some switches promise that their reaction speed reaches the ms level. A few cite more precise figures. Current switches with response time less than 200 ms are not rare.

How precise is it?

Check if the current switch assures high precision. The more precise it is, the better performance will it deliver. Check how low the hysteresis is; some switches have a hysteresis of less than 1%. Such switches can function under strong magnetic conditions. Some brands even promise 1% accuracy. The switch should leak as little as possible. You can find brands that mention that the maximum current their switches leak is no more than 0.1A.
