Abstract
A money operated control is used to control and operate a selected one of a plurality of electrical units such as washing, drying or gas dispensing machines. Each such unit includes a unit controller device operable to control the functioning of the unit upon delivery of a start signal to the unit controller device. The start signal is generated by actuating a select switch which corresponds to the desired machine. Each select switch is defined by two normally closed switches which are ganged together with a normally open switch.
