Buy impulse switches for the electric distribution installation at eibabo! We offer a large selection of quality impulse switches and remote electric switches, as well as remote switching relays, remote installation switches, cascade connections, multiple centers and call acknowledgment relays. The eibabo catalog for impulse switches also provides remote serial switches, impulse group switches and impulse series switches and impulse relays and central pulse switches. Impulse switches are usually offered in two models, for series installation for mounting on a DIN rail or for mounting in a box / junction box (flush or surface-mounted). Impulse switches are electromagnetically actuated switches, whose switching relays are switched on by an electrical impulse at the control inputs and switched off by another impulse. Technically seen, impulse switches are bistable relays. With each actuation of the connected key the impulse switch receives an electrical impulse. This causes a change in the switching state, which is stored mechanically or electronically until the next pulse. In electrical installations and electrical distribution installations, you can use impulse switches instead of breakers, toggle switches and intermediate switches. In this way, multiple switching points can switch the same device (eg. lighting in corridors or stairwells) permitting a cheaper and easier wiring of the impulse switching system than with other switching types. You can also use impulse switches with three or four switching states (impulse series switch), if you need more complex switching processes. The most common impulse switches are designed with switching coils for 12 V≃, 24 V≃ or 230 VAC. Impulse switches with monostable switching relays constantly need a small amount of electrical energy, whereas electronic impulse switches with bistable switching relay operate with virtually no stand-by loss.
