The OKTO ES12-230 is an electronic latching switch with one (normally open) contact and 230 VAC control voltage. Like all electronic OKTO latching switches, it is very quiet during operation. The latching switch can be installed in existing and new installations thanks to automatic three- or four-wire detection. The zero-crossing circuit for optimum LED switching protects the relay contact and extends the life of the lamp. The standby consumption is only 0.3 W and ensures energy-efficient operation. https://elecena.pl/product/28267725/3120130-electronic-latching-switch-1-n-o-contact-extra-quiet 2025-04-08 https://elecena.pl/product/28267725/3120130-electronic-latching-switch-1-n-o-contact-extra-quiet 2025-04-19
