Latching Relay Magnet hold latching relay
Application
To switch high power, and usually be used in the following:
- Single phase prepaid electricity meter with IC card
- Collective electricity meter reading system
- Some kinds of home-hold electronic appliance
- Some automatic controller (such as light controlling system)
Work principle
latching relay is a type of dual-stable-state magnetic hold relay which only requires power to switch the contact. The relay will keep contact or break off contact if there is a direct sufficient pulse voltage applied to the coil. Then there is not the requirement of power supply on the coil, because the on or off position of the contact can be kept by the magnet force.
Product features
- No power consumption in the hold position. Low power consumption
on the driving coil
- High contact force with low contact resistance
- Small size with reasonable structure
- High resistance to vibration and shock
- High power can be cut and be available to work under heavy
load
- Using for low frequency switch action
- High quality silver alloy for contactor
