Syringe bodies

A print material particles container, comprising:

• a syringe body including a switch and an electrical interface;
• a print material particles reservoir located in the syringe body, wherein the print material particles reservoir includes print material particles;
• an interface at an end of the syringe body including an output at a distal surface of the syringe body;
• and
• a structure to adapt a volume of the print material particles reservoir;
• wherein, in response to the volume adapting structure moving from a first position to a second position to close the switch:
• the print material particles are moved out of the print material particles reservoir, through the output, and to an imaging device;
• and
• a signal is transmitted by the electrical interface.

A system, comprising:

• a syringe body including a switch and an electrical interface at a side surface of the syringe body;
• a print material particles reservoir located in the syringe body;
• an interface at an end of the syringe body including an output at a distal surface of the syringe body;
• and
• a plunger coaxially located in the print material particles reservoir;
• wherein, in response to the plunger moving from a first position to a second position:
• the switch is closed;
• print material particles located in the print material particles reservoir are supplied from the print material particles reservoir to an imaging device;
• and
• a signal is transmitted by the electrical interface to the imaging device in response to the switch being closed to indicate the print material particles having been supplied to the imaging device from the print material particles reservoir.
