Abstract
A safety razor has a handle and a cartridge selectively detachable from the handle. The cartridge has at least one blade with a sharp cutting edge and an expected shaving utility. A connecting structure is coupled to the handle and attaches or detaches the cartridge from the handle in response to a detachment action performed by a user. A detector within the handle has an actuator coupled to the connecting structure and a sensor for generating a signal, wherein the actuator applies an action on the sensor during the action and the sensor generates the signal in response to the action.

A safety razor comprising:
- a handle and a cartridge selectively detachable from the handle, the cartridge comprising at least one blade with a sharp cutting edge and an expected shaving utility;
- a cartridge release mechanism arranged to move in a first direction coupled to the handle and configured to detach the cartridge from the handle in response to an action performed by a user;
- and
- a sensor within the razor comprising a pin member projecting from the cartridge release mechanism and a microswitch configured to generate a signal, the microswitch comprising a biased toggle member contiguous with the pin member, maintaining the microswitch in a cartridge attached state, wherein during detachment of the cartridge from the handle the pin member interacts with the biased toggle member changing the microswitch to a cartridge detached state.
