Review: Good functional switch - Used to wire a VFD so low voltage application bur works well and is the usual good quality expected from the brand.
Review: Apprezzabile la compattezza, la rotazione del comando leggera ed allo stesso tempo stabile nelle tre posizioni. I morsetti per le connessioni, predisposti per capocorda a forchetta, assicurano un collegamento elettrico e meccanico affidabile. Consigliato.
