Abstract
An improved solenoid adapted for use in a solenoid actuated valve or switch is disclosed. Increased speed of operation and increased capacity result from the incorporation of a plate or disc type of armature which is relatively unrestrained with respect to the actuating mechanism for the valve or switch device to be operated thereby, whereby the effective air gap in the magnetic circuit may be substantially reduced.
