Function:
Switches and push-buttons are components for switching consumers in industrial, commercial and private electrical installations, such as switch-disconnectors, impulse relays (remote switches) and main switches. Impulse relays, also known as remote switches, are switching relays that switch on due to an electrical impulse at the control inputs and switch off due to another impulse. They are also known as "electrical non-holding contacts". This impulse relay design also has inputs for central commands in addition to the local command inputs. The devices in series SIR were originally developed for use in the SI system. However, they can be used universally thanks to their 24 V impulse technology. This impulse relay design is suitable for mounting in electrical distribution boards.
