ABB Current impulse switch

Impulse switches are electromagnetically operated devices that enable simple, energy-saving, and safe lighting control. Typically, impulse switches are controlled via push buttons in situations where the light needs to be operated from at least three different locations. With each control pulse sent to the coil-magnet system, the device switches back to its previous position and holds this mechanically until the next control pulse. In the event of a power failure, it is ensured that the last switching position is held mechanically. This technology helps to significantly reduce electrical losses and the power consumption of the devices. Due to their very quiet switching noises, impulse switches are also suitable for use in public buildings, hotels, and private residences. Depending on the type, the devices can be controlled with standard control voltages and are designed for a rated current of 16 A or 32 A.
