Difference between trigger action and non-trigger action pushbuttons
What is the difference in size and actuation of trigger action pushbuttons
Trigger action pushbuttons are impossible to partially engage the contacts. The trigger action causes the operator to snap over from one state to the other once engaged past a point of no return. For safety applications and emergency off/stop applications, this is the preferred method. In general, trigger actuated pushbuttons are 5mm longer than the non-trigger action counterparts.
