What are non-latching relays?

Non-latching relays, also known as industrial switches, are types of electrical switches operated by electric impulses. These types of relays are used to open and close circuits.

Non-latching relays will often remain in a normally closed (NC) position and remain without power. It is only when electricity is introduced that relay switches to a normally open position (NO). The device returns to an NC position once the current is turned off.

Pushbuttons applications are therefore common for non-latching relays. You can find both latching and non-latching relays in the market, each with unique features and uses.

What is the difference between latching and non-latching relays?

One fundamental difference between a latching and non-latching relay is that a non-latching relay will return to its original position once it has been powered, whereas a latching relay will remain in the last position.

Industrial applications of non-latching relays

Non-latching relays are used across a wide range of applications including:

• Vehicle engines
• Industrial machinery
• Medical equipment
• Telecommunications equipment
• Household appliances
