1. A height adjustable workstation, comprising:
a worksurface;
a support leg coupled to the worksurface;
an electric motor coupled to the support leg, wherein the electric motor is configured to translate a movable portion of the support leg relative to a stationary portion of the support leg;
a power source;
a mechanically actuated connector coupled to the worksurface and connected to the power source, the mechanically actuated connector comprising:
a first power connector connected to the power source;
a second power connector spaced apart from the first power connector; and
a connector interlock operational between an engaged position and a disengaged position, in the engaged position, the connector interlock connects the first power connector and the second power connector, and in the disengaged position, the connector interlock disconnects the first power connector and the second power connector; and
a controller connected to the second power connector and configured to be connected to the power source via the mechanically actuated connector, the controller comprising:
a height adjustment controller connected to the electric motor;
wherein:
in the engaged position, the connector interlock connects the controller to the power source to power the height adjustment controller such that the height adjustment controller controls the electric motor to drive the movable portion to change a height of the worksurface; and
in the disengaged position, the connector interlock disconnects the controller and the power source.
