Abstract

A cost-effective ergonomic shaped suspended control panel for remotely controlling machinery, such as hoists or cranes. The suspended control panel has two curved housing portions and a curved circuit card mounted in the interior of the curved housing. Keys are mounted to the front side of the circuit card and switching devices are mounted to the back side of the circuit card. An electric line, supported by a cable, is electronically connected to the circuit card, the keys and the switching devices. The control panel is easily assembled through use of plug sockets for connecting the switching devices to the circuit board. Each plug socket is mounted with spring clamps which extend through the circuit card for wiring.
