Abstract: It is disclosed a safety interlock mechanism that comprises: a plurality of interlock switches having a first contact and a second contact; an actuator mechanically coupled to each interlock switch, the actuator having an active position wherein the actuator acts on the switch so that the first contact is in conductive state and having a passive position wherein the actuator acts on the switch so that the second contact is in conductive state; and a detection circuit connected one of the interlock switches; wherein the plurality of interlock switches are connected in series through the first contact and the detection circuit is connected to the second contact being the detection circuit an active circuit to determine the position of the actuator.

Abstract: An example device in accordance with an aspect of the present disclosure includes a first reservoir for a printable composition, a pump fluidically coupled to the first reservoir and a second reservoir, and a valve to prevent backflow from the second reservoir to the pump. The valve is to selectively isolate the second reservoir from the pump based on a threshold pump pressure under which the valve is to close.
