Advantage is taken of the fact that each switching state change (i.e., each throw) of a double throw switch requires a pair of controlled input signals to be applied to the switching element that controls that throw. By sharing input leads among several switches and by arranging the leads with respect to each switch throw element such that for any pair of leads only one switch throw element will activate, it is possible to reduce the total number of leads for the combined switch package. In one embodiment, all of the switches in a switching device are packaged as a single device.
