ABSTRACT:
An appliance timer includes a motor-driven cam, a plurality of electrical switches responsive to the cam, and a plurality of electrical terminals electrically connected to the switches, all of which are supported in a housing. The terminals are arranged on one end of the housing in n rows, and bussing between the terminals is provided so that all terminals to which external electrical connection is to be made are in one of m rows, with m being less than n. An insulating maze structure is provided in the housing within which the terminals are mounted so that the air path distance between terminals connected to differing electrical polarities is greater than the straight line path. The terminals to be connected to are longer than the other terminals. A terminal cover is snapped onto the housing and covers all of the terminals in the rows other than the m rows while leaving the longer terminals in the m rows exposed for connection to an external connector.
