摘要:
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.
