Mechanical Timer BEMKO TSMD20 with 24-hour Dial

Mechanical Timer BEMKO TSMD20 with 24-hour Dial is a simple electromechanical device for scheduled on/off control of electrical appliances. It uses a 24-hour rotating dial and mechanical segments to set multiple switching periods throughout a single day. The timer is powered from ~230 V / 50 Hz and accepts plugs of type F, providing a maximum switching current of 16 A with protection class II and IP20 enclosure rating. Operating temperature ranges from -10°C to +40°C.

Advantages

The timer provides straightforward daily scheduling without the need for electronic programming, using a durable mechanical mechanism and a clear 24-hour dial. It supports a wide range of household and small commercial loads up to 16 A and is compatible with standard type F sockets. Built to operate across common ambient temperatures, it offers reliable timed switching for lighting, pumps, heaters and similar devices.

How to use

Plug the Mechanical Timer BEMKO TSMD20 into a compatible type F outlet and connect the appliance to the timer socket. Set required on/off periods by moving the mechanical segments on the 24-hour dial to the desired times; each segment corresponds to a fixed time increment. Ensure the total connected load does not exceed 16 A and that the device is used indoors within the specified temperature range. For continuous power or manual override, use the built-in switch according to the markings on the unit.

Usage recommendations

Use the timer only with appliances whose starting and running currents are within the 16 A limit. Install and operate the device in dry indoor locations away from direct moisture or splashing; avoid exposure to temperatures outside -10°C to +40°C. Do not use the timer for medical or safety-critical equipment where failure could cause harm.
