Function: Manual control of all kinds of electrical devices.

Applications: Switching of lighting and heating in homes, shops, factories, hospitals, offices, warehouses etc.

Function: Contactors are electromechanically controlled switches used to control single or multi-phase (high) power loads while the control itself can be (very) low power.

Applications: Switching of lighting, heating-equipment, motors for pumps and fan day and night contactors are used mainly in combination with dual-applications to allow high-energy-loads (i.e. electrical water heaters accumulation heaters) only to consume energy during the low-tariff period. A forced-on, forced-off, auto-switch allows to overrule the normal operation of the DN-contactor at all times.

Function: Status visualisation

Applications: Mainly used to visualise the status of a (sub) part of the installation heater, motor, fan, pump etc.

Function: Impulses switches are electromechanically or electronically controlled switches used to control single - or multi-phase medium-power loads while the control itself can be (very) low power. The device switches between 2 stable positions, each time a (brief) impulse energises its control circuit.

Applications: Mainly used for the switching of lighting and heating equipment and/or obtain a simplified wiring in case the load needs to be controlled at reduced voltage and/or from more than 4 different places.

Function: Relays are electromechanically controlled switches used to control low power loads.

Applications: Switching of lighting, heating, etc. Galvanic insulation of i.e. status signalisation lamps from a (high) power (high voltage) circuit, Galvanic insulation of PLC-inputs or outputs to avoid destruction through excessive voltage.

Function: Protection of an electrical installation and all electrical and electronic devices connected to this installation against destructive overvoltage surges. Such voltage surges can be generated by lightening induced currents, by networkpolluting devices such as motors, frequency-converters, dimmers etc. and by power supplier network switching operations.

Applications: Surge Guard surge arresters cover the protection of home appliances (TV, HiFi, VCR, laundry-machine, dishwasher,...), commercial building equipment (computer and data communication network, intrusion and fire alarm system, access-control and building automation system), industrial equipment (PLC, instrumentation, medical apparatus, monitoring devices) and even the protection of entire off-shore drilling platforms.

Function: Conditioning of incoming impulses to exact predictable output impulses.

Function: Electronic switch controlled by the intensity of the ambient light, detected by a separate or integrated photocell (depending on the model). When the light intensity drops below the threshold setting, the switch changes its state to the on position. An increasing ambient light intensity eventually will switch off the device again.

Applications: Control of lighting in shop windows, offices, car parking areas, controlling street lights, advertising signs, sun blinds, shutters, or even lighting in a home to simulate the presence of people.

Function: Reducing the voltage to a very low (safety) voltage used mainly as control-voltage in order to reduce the risk of electrocution due to environmental circumstances (i.e. high degree of humidity like outdoors, in a swimming pool complex, etc.)

Function: Push-button operated single-shot timer, switching the power to load after the push-button has been pushed briefly, and switch again after the presented time has elapsed.

Applications: Lighting or ventilation of staircase, basements, halls, etc.

Function: Measurement, visualisation and logging of voltage, current, frequency, hours of operation, power, energy, cos , etc.
