Abstract
A switch operator, such as a manual push button, mounts a latch onto which are mounted up to four cartridges. A pair of laterally opposed arms of the latch receive each cartridge between them, and lock the cartridge to the latch. Each cartridge has four lips, two for each arm, which engage a pair of spaced apart locking surfaces on each arm. Each arm fits between the two lips it engages, and each cartridge has a pair of feet which fit into a pair of pockets in the latch. A contact cartridge has a follower, and the follower and feet are both positioned to one side of the cartridge, and the feet cooperate with the pockets to insure proper orientation of the cartridge in its position on the latch.
