Electronic impulse switch with 1 channel/contact (normally open). Comfortable light control of a common load with multiple push buttons is possible. Particularly quiet operation of the installation remote switch. High glow lamp load up to 100 mA. Automatic 3-/4-wire detection of the impulse switch. Lamp-friendly due to zero-crossing switching for high LED switching power (600 W). Standby consumption of the impulse relay is only 0.3 W. The OKTO ES12-230 is an electronic impulse switch with one contact as a normally open switch and a 230 V AC control voltage. It is ideally suited for simple lighting control in stairwells of multi-family homes as well as in purpose-built and commercial buildings, in common areas, and in private living spaces. Like all electronic OKTO impulse switches, it offers particularly quiet operation. The impulse switch can be easily integrated into existing and new installations thanks to automatic 3- or 4-wire detection. Installation is a breeze on the DIN rail (top hat rail). OKTO electronic impulse switches feature zero-crossing switching for optimal LED control. This protects the relay contact and extends the lifespan of the light source. Thus, high LED switching powers of up to 600 W are possible. The standby consumption is only 0.3 W, ensuring energy-efficient operation.
