Abstract

An electrical or electronical motor control composed of a switch and of an electromechanical component, each chosen from a group of different types of respectively switches and electromechanical components. A switch and an electromechanical component together form a control box. In a preferred embodiment, the electromechanical component includes a universal multiple pin connector whereas the switch is provided with a complementary multiple pin connector and the connection between those connectors is such that only the appropriate pins required to produce the appropriate result for a particular switch/electromechanical component combination are activated.

Claims
