Mechanically actuated force control switches protect cranes, hoists and other lifting machinery against weight or force overload as well as slack load.
The overload switches are force or weight sensing devices although they have no indicator as part of their system. Instead they shut off power when they register an overload condition, or they activate alarm lights, buzzers or klaxons to warn of impending overload.
Dyna-Switch
Dillon load limit Dyna-Switches are the economical answer to process control weighing, automation and overload applications where electrical circuits need to be activated proportional to load. Capacities from 100 lb to 50,000 lb are available with one to four control switches infinitely adjustable over the entire range.
