AutomationDirect has added SSP safety enabling switches, also known as “hold-to-run” or “dead man’s” switches. When used in conjunction with a properly designed safety system, they provide the operator with a special control mode for tasks such as maintenance or debugging of hazardous equipment.
These switches consist of a spring-return three-position (N.O.-N.C.-N.O.) grip button that must be maintained by the operator in the middle position for the machinery to continue operating.
In addition to the grip button, models are available that include a built-in E-stop button, LED indicators, additional pushbuttons for auxiliary functions, or an activity sensor to detect when the switch is in its home position. All models come in a rugged IP67 enclosure and are easy to use even with gloved hands.
The new SSP safety enabling switches and accessories start at $219.00 and come with a one-year warranty.
