Power Circuit and control limit switches are designed for use with cranes, hoists, conveyors and similar types of moving machinery in industrial applications.
Crane Power Circuit Limit Switches are mounted on a crane trolley to prevent over travel of the crane hook when hoisting. They act as a power circuit disconnect for the hoisting motor. On dc applications, a resistor is required with the limit switch to provide dynamic braking.
Control limit tack type switches are heavy-duty switches designed for use with cranes, hoists, conveyors and similar types of moving machinery. They are supplied with three non-overlapping contacts — and with spring return or maintained lever operation.
