Theben OKTO 540 BN elektronický mini impulzní spínač 5400030

Managing lighting from multiple locations can be a challenge in residential and commercial installations. The Theben OKTO 540 BN electronic mini impulse switch solves this by allowing you to control a single lighting circuit from any number of push buttons, using a simple pulse signal. It replaces traditional latching relays with a compact, silent electronic solution that fits into standard flush-mounted boxes.
