Mechanical timer switch ORNO OR-PRE-427(GS) MINI — plug-in Schuko time programmer

ORNO OR-PRE-427(GS) MINI is a compact mechanical plug-in timer switch designed for use with grounded Schuko sockets. The device provides simple, reliable on/off scheduling using a rotary 24-hour dial and movable pins to define daily switching intervals. Its small size makes it suitable for close-to-outlet installation without blocking adjacent sockets, offering basic timed control for lamps, small heaters, pumps and other household appliances with a Schuko plug.

Advantages

The mechanical construction ensures straightforward operation without the need for programming menus or batteries. A clear dial with hour markers and removable pins makes it easy to set multiple daily on/off cycles. The unit’s grounded contact and compact housing provide safe, space-saving installation in standard European sockets. The device is maintenance-free and immediately operational after plugging in.

Suitable for

• Timed control of table and floor lamps
• Automatic switching of small electric heaters (within rated load)
• Operation of aquarium or garden pumps on daily cycles
• Controlling decorative lighting and seasonal lights

Key specifications

• Type: mechanical plug-in timer for grounded Schuko sockets
• Control: 24-hour rotary dial with movable pins for daily intervals
• Installation: direct plug-in to wall socket, compact form factor
• Rated for standard household mains voltage and current (check appliance load compatibility)
• Contact configuration: single channel switching for one connected device

How to use

Plug the timer into a compatible grounded Schuko socket and insert the appliance plug into the timer outlet. Set the current time by rotating the dial to align the present hour with the indicator. Insert or remove pins around the dial to define on and off periods—pins pushed in typically represent active (on) periods while pulled out represent off periods. After setting, the timer will switch the connected appliance according to the daily schedule as the dial rotates once every 24 hours.

Usage recommendations

Verify the power rating of the connected appliance against the timer’s rated load before use. Avoid plugging in devices that exceed the timer’s capacity, and do not use the timer with equipment that requires precise timing for safety-critical functions. For outdoor or damp locations, use only weather-protected sockets or suitable enclosures.
