The TIMM analog timer is an electrical switch that closes the circuit with times defined by the operator using the two knobs on the control panel.

The first knob is marked with the label "ON SEC" and indicates the time the electrical circuit remains closed upon activation.

The second "OFF MIN" indicates the time the electrical circuit remains open between one activation and the next.

It is suitable for use as a control for the SCT-.. timed automatic discharge system (see above).
