Impulse switch UC. 1 NO contact potential-free 10A/250V AC, 230V LED lamps up to 200W, incandescent lamps 2000W. No stand-by loss. For recessed mounting. 45mm long, 45mm wide, 18mm deep. State-of-the-art hybrid technology combines the advantages of wear-free electronic control with the high performance of special relays. Either universal control voltage 8..230V UC at control input +A1/-A2 or 230V with up to 5mA glow lamp current at control input with glow lamp symbol (L)/-A2(N). Simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No permanent power supply required, therefore no stand-by loss. Due to the use of a bistable relay, there is no coil power loss and no heating due to this, even when switched on. The relay contact can be open or closed at start-up and synchronises itself at the first actuation. If this impulse switch is in a circuit that is monitored by a FR12-230V field disconnector, it does not require an additional base load, but the monitoring voltage of the FR12-230V must be set to max. The electronics have no power supply of their own and therefore no power consumption in either contact position. Only during the short control pulse of only 0.2 seconds does the control current flow, which activates the microcontroller, lets it read the last switching state from its non-volatile memory, switches the bistable relay accordingly in the opposite direction and writes the new switching state back into the memory.
