Abstract: An electrical connector for insulating a connection between at least two wires. The connector includes a cup shaped casing and an inner core, each having a closed end and an open end. The inner core is received within the casing defining a fully enclosed sealed cavity therein in which an insulating compound is received. The casing includes an end wall which has a plurality of recesses extending inwardly of a surface thereof terminating in thin covering membrane. A piercing member is provided for forming apertures in each of the membranes for receipt of a wire therethrough, said apertures each having a diameter slightly less than an associated wire extending therethrough providing a snug fit therearound, thereby sealing the connector cavity.

Abstract: A program expander for a sprinkler valve timer, alternates a pair of valve selector switches each having a plurality of sprinkler valves connected thereto. The expander includes a star wheel attached to the shaft of a double wafer rotary switching arrangement and a lug on a motor driven timing disk which engages the star wheel once at the end of each revolution thereof, thereby advancing the switching arrangement one position. The expander further includes a bank selector switch which connects valve actuating power alternately to one valve selector switch and then the other, and a disk motor switch which delays disconnecting the disk motor until the end of every other revolution of the disk in cooperation with a motor stop switch actuated by the timing disk and operative to disconnect the disk motor switch at the end of each revolution of the disk.
