Electromechanical pulse switch with 1 channel/contact (normally open). Comfortable light control of a common load with multiple push buttons is possible. Simple and cost-effective electrical installation with 2 wires per button. Operation via the integrated manual switch on the pulse switch is possible. Potential-free with safety extra-low voltage (SELV). LED switching load up to 200 W. No standby power consumption of the pulse relay. The OKTO S12-230 is an electromechanical pulse switch with one contact as a normally open switch and a control voltage of 230 V AC. It is ideally suited for simple lighting control in stairwells of multi-family homes as well as in utility and commercial buildings, in common areas, and in private living spaces. With the OKTO pulse switch, comfortable light control from any number of switches can be implemented easily and quickly. Thus, only 2 wires per button are needed for the electrical installation. Mounting is a breeze on the DIN rail (top hat rail). The OKTO electromechanical pulse switches can also be operated via the integrated manual switch. The potential-free OKTO S12-230 pulse relay allows for an LED switching load of 200 W.
