A Shabbat-mode refrigerator is a standard cooling appliance equipped with a setting that alters its electrical behaviour during Shabbat.

In conventional operation, opening the door activates
interior lights, sensors, alarms, and may influence compressor activity. The appliance is designed around immediate feedback between gesture and
system response.

Before manufacturer-supported Shabbat modes became widespread, users improvised. Light switches were taped over. Bulbs were removed. As one participant recalled, “We used to remove the light bulb. Today, with new refrigerators, that’s no longer possible”. These manual interventions physically interrupted the causal chain between door opening and electrical activation.

Shabbat Mode formalizes this workaround. Interior lights remain off. Sensors and alarms are disabled. Cooling cycles proceed independently of door openings, often on fixed or delayed intervals. Certification bodies such as Star-K collaborate with manufacturers to ensure that opening the door does not directly trigger electrical change.

An engineer described this configuration as making the refrigerator behave “like a 1950s model.” The reference is not nostalgic but temporal: the appliance operates without smart sensors or real-time responsiveness. Its internal processes follow their own cycle rather than reacting to the user.

Opening the door remains physically possible, yet it no longer produces an immediate electrical response. The system continues running, but without coupling gesture to consequence.

Within the home, such arrangements are learned through repetition. Evening routines form. Periods of rest are anticipated. Certain actions are postponed, others are brought forward. Time is not merely measured. It is shaped through material arrangements that sustain durations, mark transitions, and regulate intervention.

Design gives form to timescapes.

• A bell signals a beginning.

• A timer holds a duration.

• A switch interrupts or restores continuity.

Through these mechanisms, design determines when action is possible and when it is withheld. Agency is distributed across time rather than concentrated in a single moment. Some actions require immediate response, while others are displaced into preparation, waiting, or automatic unfolding.

Design does not merely operate in time. It organises temporal conduct.

In many contemporary consumer technologies, this organisation stabilises a particular timescape. One in which action remains continuously available, interruption is expected, and control is exercised through frequent checking and adjustment. Time is broken into short cycles of response. Continuity is maintained through repeated intervention rather than sustained absence.

This is not the only timescape design can sustain.

Approaching design through timescapes makes visible how objects and systems structure temporal relations: when anticipation is required, when waiting is imposed, when responsibility is exercised in advance, and when action is deliberately withdrawn. Time appears not as a neutral background, but as a condition actively shaped by material design.
If acceleration dominates contemporary temporal regimes, restriction becomes an alternative way of designing time.
