What is the difference between the Safety
Limit Switches and the General Limit Switches?
The Safety Limit Switches are provided with
a direct drive positive opening mechanism (positive actuation structure)
with which welded portions are forcibly torn even if contact welding
occurs, thus stopping a dangerous process (load) without fault and
performing safe operation.
On the other hand, the General Limit Switches are not provided with the
above mentioned mechanism. Therefore, if contact welding occurs, it keeps
conduction state, and thus it cannot reliably stop dangerous process
(load) and may perform dangerous operation.
For this reason, use the Safety Limit Switches in applications for safety
