When additional interlocking is required, which component is sometimes used?

The use of pushbutton interlocks is effective in situations where operational safety and control are paramount. A pushbutton interlock requires the operator to press a designated button before a certain action can take place, ensuring that the machine or system cannot be activated under unsafe conditions. This physical action reinforces the need for attention and intentionality from the operator, significantly reducing the risk of accidental operation of equipment.

In environments where additional interlocking mechanisms are necessary, pushbutton interlocks provide an intuitive and easily recognizable way for operators to confirm that specific conditions are met before proceeding. This can be particularly useful in setups where there are multiple processes happening simultaneously, ensuring that the appropriate checks are in place without complicating the control scheme excessively.

While other interlocking methods, such as mechanical or electrical interlocks, do play their roles in ensuring safe operations by physically preventing movement or providing automatic safety shutdowns, the pushbutton interlock stands out for its user-operated activation, fostering increased operator engagement and control over safety procedures.
