Ready light circuit is provided comprising a simple third switch blade added to standard thermostat two-blade switch in electric iron. Light is activated when bimetallic element of switch drives third blade into engagement with other blade as iron reaches set temperature. Light stays illuminated as long as main contacts of standard-type blades remain open. When thermostat calls for more heat, light in circuit which is across main contacts, is shorted out.

In an electric pressing iron having a heater circuit, the iron having mounted on the top of its soleplate a temperature-sensitive switch comprising a pair of superposed, spaced aligned contact blades cantilever-mounted and extending in the same direction, the switch including an upper blade and a lower blade, the blades carrying aligned contact zones, a bimetallic element cantilever-mounted on the soleplate in heat exchange relation therewith and adapted to engage with its distal end the lower blade to move the distal end of said lower blade away from the upper blade in conditions of no-heat-demand to separate the contact zones, temperature control setting means on the iron including means to raise and lower the distal end of the upper blade, the heater circuit being operatively connected in series with the switch, the improvement of a ready light circuit including a third blade mounted cantilever-fashion and disposed between and generally aligned with the other blades, the upper blade and third blade having aligned contact points, the bimetallic element adapted in conditions approaching heat-demand to cause upward movement of the distal end of the third blade to adjacent the upper blade to close the contact points, the ready light and the contact points being operatively connected in series and across the contact zones of the upper and lower blades.
