ABSTRACT:
A key actuated tubular lock capable of a plurality of locking operations, each with switch operating capability, includes a substantially cylindrical outer barrel, key actuated locking spindle means, including a stationary sleeve and a rotatable sleeve, disposed within the barrel and a multiple operation switch operating assembly rigidly attached in a removable manner and adapted to be operated by rotation of the locking spindle through use of a proper key. The multiple operation assembly includes a switch subassembly, having a microswitch and a switch operating member associated therewith, positioned within a switch retention area in the rear end portion of the barrel in such a way that the operating member is contacted so as to turn the microswitch "off" when the locking spindle is in a first position and "on" when the spindle is key actuated to a second position. The various components of the multiple operation switch assembly are adapted to be assembled according to a plurality of arrangements so that they coact differently with each other and with the stationary sleeve, thereby providing the plurality of locking operations for the lock along with switching capability.
