variable thermal time delay switch

The light timing switch is a timing circuit with which different switching times can be assigned to a plurality of parallel-connected switches.

A manually operable timer switch (24) is operated to energize the heating mechanism and to select a time period for maintaining the heating mechanism energized.

In case of power failure and the lift is between two floors, a timed switch opens the first electromagnetic valve (26), thereby displacing the core (30) on the basis of pressure differences.

A personal heat control has a housing (4) accommodating a Peltier-effect unit (1), one or more batteries (15) and a timing switch (9) for selective energisation of the unit (1).
