ABSTRACT:
The cartridge is interchangeably structured to accommodate various servomechanisms for the switch or other operating unit therein, as well as to accommodate various electrical arrangements for the pushbutton cap which is slidably guided in the open end of the cartridge to operate the servomechanism. The cap is releasably latched to each servomechanism by a cross-biased latch mechanism which prevents the cap from being shocked out of the cartridge, but which can nevertheless be overridden by a finger pull on the cap when it is desired to remove the cap from the cartridge. When so removed, the cap is tethered to the cartridge, although the tether is releasable from the cap, and vice versa, should this become necessary or desirable.
