Mechanical time switch with dusk sensor ORNO OR-PRE-445(GS) Schuko 16A 230V

The Mechanical time switch with dusk sensor ORNO OR-PRE-445(GS) Schuko 16A 230V is a wall-mounted mechanical timer that combines scheduled on/off switching with an integrated dusk-to-dawn sensor. Designed for direct connection to a Schuko outlet, this device supports resistive and inductive loads up to 16 A at 230 V and is intended for timed control of lamps and small appliances in homes and small commercial spaces. The mechanical dial and pins provide straightforward programming while the twilight sensor enables automatic operation based on ambient light levels.

Advantages

This ORNO mechanical time switch offers reliable mechanical scheduling without the need for software setup, ensuring simple installation and predictable operation. The built-in dusk sensor adds automatic night-time switching, reducing the need for manual intervention and improving energy efficiency. Compatible with standard Schuko outlets and rated for 16 A at 230 V, it accommodates a wide range of lighting and small appliance loads when installed according to local electrical regulations.

Suitable for

• Timed switching of indoor and outdoor lighting (with appropriate weatherproofing)
• Control of garden or balcony sockets for lights and small equipment
• Energy-saving scheduled operation of lamps in homes or small shops
• Simple automation of devices that require daily on/off cycles tied to daylight

Key specifications

• Power supply: 230 V AC
• Maximum switching current: 16 A
• Type: mechanical dial timer with pins
• Integrated dusk (twilight) sensor for automatic night-time activation
• Output: Schuko-type socket compatible with standard plugs
• Designed for lamps and small household or commercial appliances

How to use

Install the time switch into a standard Schuko socket or have it mounted by a qualified electrician following local wiring rules. Set the current time on the mechanical dial, insert or remove the scheduling pins to define on/off intervals, and adjust the dusk sensor sensitivity if an adjustment is available. Plug the lamp or appliance into the Schuko outlet of the timer. The device will switch according to the mechanical schedule and will also turn on automatically when ambient light drops below the sensor threshold, and off when light returns, depending on the selected settings.

Usage recommendations

Use the timer with luminaires and devices within the specified current rating and protect outdoor installations with appropriate weatherproof housings. For inductive loads such as motors or transformers, verify compatibility and consider surge protection. Periodically check mechanical pins and the dial for correct positioning to maintain accurate scheduling.
