Abstract
A switch is disclosed. In some examples, a switch includes a generally cylindrical housing; one or more sets of contact points enclosed by the housing; an indicator module, such as a multi-color LED illuminator, also enclosed by the housing; and a pushbutton actuator disposed to operate the contact points. The housing includes a display section spanning substantially the entire circumference of the housing such that the indication made by the indicator module is visible from all radial directions. When the pushbutton actuator is pressed, some of the contact points open to cut off power from hazards, while others are reconfigured to change the state of the indicator module to indicate the changed status of the switch. Multiple switches can be interfaced with each other, such as by serial connection, to facilitate multi-switch safety environment. Modular cables can be used to conveniently establish the interface.
