Pulse relays are electromagnetically operated devices that enable simple, energy-saving, and safe lighting control. Typically, pulse relays are controlled via push buttons in situations where lighting needs to be operated from at least three different locations. With each control pulse sent to the coil-magnet system, the device returns to its previous position and holds it mechanically until the next control pulse. In the event of a power failure, the last switching position is mechanically maintained. This technology helps to significantly reduce electrical losses and the power consumption of the devices. Due to their very quiet switching sounds, pulse relays 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.
